[Mapzen Search](https://mapzen.com/products/search/) is a modern, geographic search service based entirely on open-source tools and open data.

Through a process known as [geocoding](https://en.wikipedia.org/wiki/Geocoding), Mapzen Search allows you to enter an address or the name of a landmark or business, and the service translates the result into geographic coordinates for mapping.

One form of address interpolation involves drawing a line that connects between the nearest known house numbers and placing the interpolated address within a range on that line.

One form of address interpolation involves drawing a line that connects between the nearest known house numbers and placing the interpolated address within a range on that line. This process may work if the road is straight, but often results in the interpolated point being placed at a distance offset from the road network on curved sections.
To improve upon the straight line technique, the Mapzen Search interpolation implementation considers the actual shape of the street when locating a point without a matching address. This results in more accurate location estimation because the interpolated addresses points are placed on the road itself, which also makes it easier for routing and turn-by-turn navigation services to calculate directions for that location.

## Caching to improve performance ## Caching to improve performance
Mapzen Search uses caching to serve commonly requested content as quickly as possible. An edge cache, also known as a content delivery network (CDN), is a network of computers, geographically spread across the world, designed to shorten the physical distance data must travel to you so it can get there faster. If you have ever tried to access a common service and found that it is slow, it may be because the information must travel a large physical distance. Mapzen Search uses a CDN to help reduce this effect and limit the impact of common queries on its application servers. Pelias uses caching to serve commonly requested content as quickly as possible.

If you have ever tried to access a common service and found that it is slow, it may be because the information must travel a large physical distance. Pelias uses a CDN to help reduce this effect and limit the impact of common queries on its application servers.
When you send a request to Mapzen Search, it first goes to the CDN server that is the closest path from your internet service provider before it is forwarded onto a Mapzen Search application server. Mapzen Search uses [Fastly](https://www.fastly.com) for its CDN; you can look at this [network map](https://www.fastly.com/network-map) to see where your requests are likely being sent.

Mapzen Search uses [Fastly](https://www.fastly.com) for its CDN; you can look at this [network map](https://www.fastly.com/network-map) to see where your requests are likely being sent.
If your request is not found in the current CDN cache, the CDN server then passes it to one of the Mapzen Search application servers. When it comes back with a response to your API call, the CDN server keeps a copy of that response (minus any personal data to your application, including your API key). If you or another nearby user makes the identical API call, you will likely be sent to the same CDN server, which has the response in its local cache. From tests in the Mapzen offices in New York, this has the effect of shortening a query from 190ms to 21ms. Your speed improvements may vary, as requests from other locations and internet providers may be served by different edge cache servers.

[Mapzen Search](https://mapzen.com/projects/search) is a modern, geographic search service based entirely on open-source tools and powered entirely by open data. Through a process known as [geocoding](search.md), Mapzen Search allows you to use natural language to find a particular place by entering an address or the name of a landmark or business, and then translates the result in to the geographic coordinates used by computers.
Mapzen Search accesses [global databases](data-sources.md) of place names and locations, but you can receive more locally relevant search results by limiting the search to a particular radius around a location (such as a cell phone), region, or country. With text [autocompletion capabilities](autocomplete.md), you can search for places and match against Mapzen Search data in real-time.
Mapzen Search also enables the opposite workflow, known as [reverse geocoding](reverse.md), to transform latitude and longitude values in to a list of places. This process attempts to find the name and address of the place nearest a longitude and latitude pair. For example, you can click a position on the map to learn which business is located there.
## Features of Mapzen Search
- [Forward geocoding](search.md) to find a place by searching for an address or name
- [Reverse geocoding](reverse.md) to find what is located at a certain coordinate location
- [Autocomplete](autocomplete.md) to give real-time result suggestions without having to type the whole location
- [Global coverage with prioritized local results](search.md#prioritize-results-by-proximity)
- Open-source software using [open data sources](data-sources.md)
- [Tools for embedding search](https://mapzen.com/documentation/mapzen-js/search/) in a map

# Mapzen Search: Finding places # Pelias: Finding places
Geospatial search, commonly referred to as geocoding, is the process of matching an address to its corresponding geographic coordinates. Geocoding is the process of matching an address or other text to its corresponding geographic coordinates.
There's nothing inherent in the language we use to describe a physical address that allows us to convert that human readable sentence in to a format that a computer can understand, such as latitude & longitude. All Pelias requests share the same format:
Making the leap from text to coordinates is an intricate and challenging process. Lucky for you, Mapzen has done all the hard work and made it accessible though a web service.
All Mapzen Search requests share the same format:
``` ```
https://search.mapzen.com/v1/search?text=London&api_key= https://search.mapzen.com/v1/search?text=London
\___/ \_______________/\__/\_____/\__________/\_______/ \___/ \_______________/\__/\_____/\_________/
| | / | | | | | / | |
scheme domain version path query authentication token scheme domain version path query
``` ```
In addition, you can search at `https://search.mapzen.com/v1/search/structured` to look for individual components of a location.
Mapzen Search works over HTTPS and HTTP. You are strongly encouraged to use HTTPS for all requests, especially for queries involving potentially sensitive information, such as a user's location or search query.

For example, you want to find `30 West 26th Street, New York, NY`. With the geocoding parameter for `search`, you can only enter the entire location as one string, such as `text=30 West 26th Street, New York, NY`. However, with `search/structured`, you can specify that this location is composed of a street address, a locality, and a region. For example, you want to find `30 West 26th Street, New York, NY`.

# Mapzen Search: Beta to V1 transition guide
First of all, thank you for being an early user of Mapzen Search/Pelias. You trusted the idea of a modern geocoding service built by and for the open mapping community and have helped make that happen.
This project is moving out of the beta stage and has an updated API designed to support the next several generations of progress to Pelias and Mapzen Search.
The changes aren't too drastic and should be implementable in an afternoon or a day at most for existing users.
These changes also affect self-hosted users of Pelias upgrading from the beta to 1.0 (leaving aside API key restrictions), but these users can make the upgrade on their own time.
## API keys
The first big change is the introduction of API keys. Like all other Mapzen APIs, Search now requires an API key. You can register at the [Mapzen Developer Portal](https://mapzen.com/developers) and generate one (or more) for all your search needs.
Mapzen Search API keys allow you:
* 6 requests per second
* 30,000 requests per day
To start using an API key, append `&api_key=mapzen-xxxxxx` to all API calls to all endpoints (aside from `/attribution`, which requires no key).
Your API usage limits are displayed in the HTTP headers of any API call, such as in this example:
```
X-ApiaxleProxy-Qpd-Left:4828
X-ApiaxleProxy-Qps-Left:4
```
## Changes to domain and URL structure
Mapzen Search is now hosted on the `search.mapzen.com` domain. The former domain, `pelias.mapzen.com` has been deprecated. To take advantage of the full v1 API, you must use the `search.mapzen.com` endpoint.
Additionally, all endpoints are now under the `/v1` namespace. For example, the full URI to the `/reverse` endpoint is now `https://search.mapzen.com/v1/reverse`.
Requests going to `pelias.mapzen.com` will continue to work until the end of November, 2015, at which point the servers handling pre-v1 requests will be disabled.
## Changes to response document
The response document is still plain, vanilla GeoJSON. Dots will still show up without a problem! Take a look at the [specification document](https://github.com/pelias/geocodejson-spec/blob/master/draft/README.md) or the [sample response](https://github.com/pelias/geocodejson-spec/blob/master/sample.geo.json?short_path=7cdb999) for further details.
### Metadata
The GeoJSON result object now contains a `geocoding` property that has lots of information about the request, such as how Mapzen Search parsed your query, certain explicit errors and warnings, and an attribution link.
### Features
The bulk of a valid response is still an array of `Feature` objects, ordered by result ranking (most relevant result first).
If the only property you used before was `text` for what to display, you'll have to change it to `label` and you'll be ready to process responses.
| Used to be (Beta) | Is now (V1) | Notes |
| ----------------- | ----------- | --------------- |
| `text` | `label` | The suggested display text. You can construct your own from the elements passed along, but this is Mapzen Search's best understanding of how to display it. |
| `layer` | `layer` & `source` | Some layers were not attributes, but sources the data was derived from. This has been split out into a separate field (see Search/Layers below for full explanation). |
| `admin0` | `country` | Now with Human Readable:tm: |
| `admin1` | `region` | States and provinces |
| `alpha3` | `country_a` | Three-character abbreviation for country |
| `admin1_abbr` | `region_a` | Region abbreviation (such as NY = New York, usually two characters) |
| `locality` | `locality` | No change|
| `neighborhood` | `neighbourhood` | Note change in spelling |
| `category` | Deprecated | This functionality is in progress and should be available soon. |
| `address:{}` | | Address elements are no longer grouped into their own object |
| `address:{zip}` | `postalcode` | |
| `address:{number}` | `housenumber` | |
| `address:{street}` | `street` | |
## Changes to `/search`
Most parameters (and options) for search have been renamed:
| Used to be (Beta) | New parameter (V1) | New behavior (if any) |
| ---------- | ------------- | --------------------- |
| `input` | `text` | |
| `lat` / `lon` | `focus.point.lat` / `focus.point.lon` | Biases search results toward places nearby, without excluding global matches |
| `zoom` | `focus.viewport.min_lon`, `focus.viewport.min_lat`, `focus.viewport.max_lon`, `focus.viewport.max_lat` | Passing along information about how far out an end-user is looking is now accomplished by passing along the end-user's viewport. Why judge just from a centerpoint and a zoom level when you can see what the user's seeing? |
| `size` | `count` | Number of responses. Minimum: 1, maximum: 50 |
| `layers` | `layers` (SEE BELOW) | While the parameter remains the same, the options have changed. See the table below for a description.|
| `bbox` | `boundary.rect.min_lon`, `boundary.rect.min_lat`, `boundary.rect.max_lon`, `boundary.rect.max_lat`| Bounding box parameters are now individually specified to prevent error.|
| `details` | Deprecated (for the moment) | `details=false` used to respond with a minimized set of elements. Mapzen is reevaluating which elements of the response document make most sense for minimization. If you've got opinions, let us know at [search@mapzen.com](mailto:search@mapzen.com)|
`layers` used to be opaque about many of the kinds of places they represented (particularly the administrative layers). `layers` were also used to retrieve places from a particular source. `sources` is now a separate parameter from `layers` to help improve clarity.
| Beta | V1 | Represents |
| -------------- | ------------ | ---------------- |
| `layers=geoname` | `sources=geonames` or `sources=gn` | [All manners of places](http://www.geonames.org/export/codes.html) from Geonames |
| `layers=osmnode` | `layers=venue,address&sources=openstreetmap` | Venues (points of interest) and all places with addresses from OpenStreetMap|
| `layers=osmway` | `layers=venue,address&sources=openstreetmap` | Streets and highways with addresses |
| `layers=admin0` | `layers=country` | Countries|
| `layers=admin1` | `layers=region` | Provinces and states (for the most part) |
| `layers=admin2` | `layers=county` | Things within states that often aren't cities, but sometimes are.|
| `layers=neighborhood` | `layers=neighbourhood` | Neighbourhoods (within localities, may be [macrohoods](http://whosonfirst.mapzen.com/spelunker/placetypes/macrohood/), neighbourhoods, or [microhoods](http://whosonfirst.mapzen.com/spelunker/placetypes/microhood/)) |
| `layers=locality` | `layers=locality` | |
| `layers=local_admin` | `layers=localadmin` | Local administrative areas (such as New York City, encompassing the five boroughs of NYC, which are themselves independent counties)|
| `layers=osmaddresses` | `layers=addresses&source=openstreetmap` | Addresses from OpenStreetMap|
| `layers=openaddresses` | `source=openaddresses` | Addresses from OpenAddresses |
| `layers=poi` | `layers=venue` | Places with walls |
| `layers=admin` | `layers=coarse` | Shortcut for coarse geocoding layers (see below) |
| `layers=address` | `layers=address` | |
So the new, valid `layers` values are:
* `venue`
* `address`
* `neighbourhood`
* `localadmin`
* `locality`
* `county`
* `region`
* `country`
* `coarse`
And the `sources` values are:
* `openstreetmap` or `osm`
* `geonames` or `gn`
* `openaddresses` or `oa`
* `quattroshapes` or `qs`
## Additions
| New | What's it do? |
| ------------ | ------------- |
| `sources` parameter | Pick the data source (separate from `layers`) |
| `boundary.circle` | Bounding circle. Like a bounding box, but circular. Takes, `boundary.circle.lon`, `boundary.circle.lat`, and `boundary.circle.radius` (in kilometers) |
| `boundary.country` | Search only within a particular country. Takes Alpha-2 or Alpha-3 country code abbreviations.|
## Coarse search
Coarse search (looking for countries, regions, counties, localities, neighbourhoods), were available on `/search/coarse`. This is now handled as a layer on search.
A former query for a coarse geocode may have been:
`https://pelias.mapzen.com/search/coarse?input=<search-text>`
That same query would now be written as:
`https://search.mapzen.com/v1/search?text=<search-text>&layers=coarse&api_key=<mapzen-xxxxxx>`
You can also call the coarse layers directly, namely, `country`, `region`, `county`, `locality`, `neighbourhood`, to restrict the kinds of results you'll get back.
Feel free to mix and match these layers with `boundary` parameters, particularly `boundary.country` if you want to restrict your results to a particular country.
## `/autocomplete` (formerly `/suggest`)
The `/autocomplete` endpoint serves as a renamed `/suggest` to show that these are not recommendations. It is subject to many of the same changes as `/search`:
| Used to be (Beta) | New parameter (V1) | New behavior (if any) |
| ---------- | ------------- | --------------------- |
| `input` | `text` | Required |
| `lat` / `lon` | `focus.point.lat` / `focus.point.lon` | Biases search results toward places nearby, without excluding global matches. No longer required for `/autocomplete` |
| `size` | Deprecated | Responds with 10 results every time |
| `zoom` | Deprecated | |
| `layers` | Deprecated | |
| `bbox` | Deprecated | |
| `details` | Deprecated | |
### Deprecated endpoints
- `/suggest/coarse`
- `/suggest/nearby`
## `/reverse`
Reverse geocoding finds the places closest to geospatial coordinates.
```
https://search.mapzen.com/v1/reverse?point.lon={longitude}&point.lat={latitude}&api_key=mapzen-xxxxxx
```
Used to be (Beta) | New parameter (V1) | New behavior (if any) |
| ---------- | ------------- | --------------------- |
| `lat` / `lon` | `point.lon` / `point.lat` | Required |
| `layers` | `layers` | same set of layers as for `/search` |
New parameters:
- `boundary.circle` - use `boundary.circle.radius` to set the distance for a reverse point search in kilometers
- `boundary.country` - Restricts reverse geocodes to a particular country based on alpha2 or alpha3 country codes
### Reverse coarse geocoding
Reverse coarse geocoding is not a point-in-polygon lookup (finding the hierarchy for the polygon that the point falls in), but instead looks for the hierarchy of points nearby. To use reverse coarse geocoding, use:
```https://search.mapzen.com/v1/reverse?point.lon={longitude}&point.lat={latitude}&layers=coarse&api_key=mapzen-xxxxxx
```
## `/place` (formerly `/doc`)
`/place` is used to retrieve the underlying place record behind a particular result.
If a search returns `id: "geonames:3544:adm1:fr:fra:paris"` as the matching ID for a record, the complete underlying place record can be returned with:
```
https://search.mapzen.com/v1/place?ids=geonames:3544:adm1:fr:fra:paris&api_key=mapzen-xxxxxx
```
## Security
### In-browser cross-site scripting
If you were using Pelias from within a browser with client-side JavaScript (using Pelias on a domain that is different mapzen.com), you should know that Mapzen Search does not support JSONP requests to get around cross-site scripting limitations.
Instead, Mapzen Search supports [Cross-Origin Resource Sharing](https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS) (CORS), which enables secure cross-site data transfers.
Mapzen Search is set to allow CORS requests from all domains.
### HTTPS
Mapzen Search continues to support HTTPS and traditional HTTP. You are encouraged to use HTTPS instead of HTTP, especially when handling sensitive personal information (such as users' searches or users' location data).
## What's happening to pelias.mapzen.com?
The beta API available at pelias.mapzen.com will be available through the end of November, 2015. Starting December 1, 2015, you will only be able to use search.mapzen.com or your own hosted version of Pelias.

`CORS` is the recommended standard for allowing your web browser and a web server to negotiate and allow requests to be made across domain contexts. `CORS` is supported in modern Chrome, Firefox, Safari, and Internet Explorer (10+) web browsers.

You don’t need to do anything special to use `CORS` with JavaScript in a modern browser. Your web browser and the Mapzen Search servers will automatically negotiate the cross-origin request. For example, to make a `CORS` request with `jQuery`, you’d make your request like you were performing it within the context of your own domain.
