+
+// This query is a departure from traditional Pelias queries where textual
+// names of admin areas were looked up.  This query uses the ids returned by
+// placeholder for lookups which dramatically reduces the amount of information
+// that ES has to store and allows us to have placeholder handle altnames on
+// behalf of Pelias.
+//
+// For the happy path, an input like '30 West 26th Street, Manhattan' would result
+// in:
+// neighbourhood_id in []
+// borough_id in [421205771]
+// locality_id in [85945171, 85940551, 85972655]
+// localadmin_id in [404502889, 404499147, 404502891, 85972655]
+//
+// Where the ids are for all the various Manhattans.  Each of those could
+// conceivably be the Manhattan that the user was referring to so so all must be
+// queried for at the same time.
+//
+// A counter example for this is '1 West Market Street, York, PA' where York, PA
+// can be interpreted as a locality OR county.  From experience, when there's
+// ambiguity between locality and county for an input, the user is, with complete
+// metaphysical certitude, referring to the city.  If they were referring to the
+// county, they would have entered 'York County, PA'.  The point is that it's
+// insufficient to just query for all ids because, in this case, '1 West Market Street'
+// in other cities in York County, PA would be returned and would be both jarring
+// to the user and almost certainly leads to incorrect results.  For example,
+// the following could be returned (all are towns in York County, PA):
+// - 1 West Market Street, Dallastown, PA
+// - 1 West Market Street, Fawn Grove, PA
+// - 1 West Market Street, Shrewsbury, PA
+// etc.
+//
+// To avoid this calamitous response, this query takes the approach of
+// "granularity bands".  That is, if there are any ids in the first set of any
+// of these granularities:
+// - neighbourhood
+// - borough
+// - locality
+// - localadmin
+// - region
+// - macroregion
+// - dependency
+// - country
+//
+// then query for all ids in only those layers.  Falling back, if there are
+// no ids in those layers, query for the county/macrocounty layers.
+//
+// This methodology ensures that no happened-to-match-on-county results are returned.
+//
+// The decision was made to include all other layers in one to solve the issue
+// where a country and city share a name, such as Mexico, which could be
+// interpreted as a country AND city (in Missouri).  The data itself will sort
+// out which is correct.  That is, it's unlikely that "11 Rock Springs Dr" exists
+// in Mexico the country due to naming conventions and would be filtered out
+// (though it could, but that's good because it's legitimate)
