Hi, today GeoData spatial searches were switched from Solr to Elasticsearch, for now only on testwiki. We're going to test it there for a while before proceeding to production wikis. Suggestions where to start are welcome - while GD is populated on many projects, it is rarely used with a few exceptions: 5825 eswiki 2046 enwiki 223 zhwiki 216 svwiki 155 fawiki 130 ruwiki 100 dewiki 75 itwiki 61 frwiki 55 arwiki 54 jawiki
I would like to start with one project, however only itwiki and kowiki are using Elasticsearch among large Wikipedias.
And finally, appreciation: this was made possible only thanks to awesome help from our search team, Nik Everett and Chad Horohoe. You kick ass guys!
