a boost query containing the terms (if any) returned by a geocode action
is now applied to the solr query.  The boost queries are removed when
the term is removed from the "where" box.

The applied boost queries take the "long_name" from the geocoder and
query the fields PlaceKeywordSynonyms and LayerDisplayName.
