/** |
|
This view (unfortunately) requires autocomplete to use the phrase.* index. |
|
|
|
ideally we wouldn't need to use this, but at time of writing we are unable |
|
to distinguish between 'complete tokens' and 'grams' in the name.* index. |
|
|
|
this view was introduced in order to score exact matches higher than partial |
|
matches, without it we find results such as "Clayton Avenue" appearing first |
|
in the results list for the query "Clay Av". |
|
|
|
the view uses some of the values from the 'search_defaults.js' file to add an |
|
additional 'SHOULD' condition which scores exact matches slighly higher |
|
than partial matches. |
