This adds support for custom boosts to the addressit-style search
queries. The newer libpostal based queries do not include this
functionality since they can only query for addresses.
By definition, all boundary.country query matches will either be
identical, or not a match. Thus, it does not make sense to put the query
clause for boundary.country in the `must` section of the query.
In theory, because our queries would generally combine this `must`
clause with others, there shouldn't be any performance improvement (or
regression) from this change.
However, semantically, this clause fits better as a `filter`, and in the
case of a bug causing a degenerate query with the `boundary.country`
query clause as the only one under the `must` section, this would have a
big impact.
the tests removed were testing far more than was appropriate since the functionality of the individual sanitisers is tested elsewhere. in this case, the test has been reduced to just testing that all the sanitisers were actually called.
add support for FallbackQuery and GeodisambiguationQuery from the pelias-query module. GeodisambiguationQuery is used when the text-analyzer returns a single administrative area field. FallbackQuery is used otherwise.
peliasAdmin was supposed to be a parameter to the multi match view, but
instead it was being sent to the score view and ignored.
Thanks to @trescube for catching this.
This simply reuses the focus:point:{lat|lon} variables, but sets them
using the centerpoint of the viewport. Eventually we should calculate a
radius and use that here.
Using the check-types module, check that lat/lon values are numbers,
instead of checking their truthyness, to ensure that queries for null
island work correctly.
