This week we shipped a new feature at the request of the mobile apps team, geo integration to full text search. 

(bare bones) Documentation: https://www.mediawiki.org/wiki/Help:CirrusSearch#Geo_Search

Quick example usage for bounded geo search:

https://people.wikimedia.org/~ebernhardson/mapsearch.html#San_Francisco|hastemplate:"National_Register_of_Historic_Places_in_California"
https://people.wikimedia.org/~ebernhardson/mapsearch.html#200km,Moscow|incategory:Kremlins

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:
