This week we shipped a new feature at the request of the mobile apps team, geo search.
(bare bones) Documentation: https://www.mediawiki.org/wiki/Help:CirrusSearch#Geo_Search
Quick example usage for bounded geo search:

Direct search example:

Also implemented a "boost" version which increases the search score of pages within a particular area, rather than the default which limits to a geographic area. Compare:
