==Discussions==

=== Search === * Erik fixed a rarely occurring issue where the ApiQuerySearch.php call to a member function termMatches() on a non-object (boolean) [5] * David turned off an A/B test for relaxing the retrieval query filter and analysis will begin soon [6] [7] * David also reviewed and update the mjolnir kafka implementation on large feature sets [8] * We ran a full re-index of un-fallbacked languages on Monday, Oct 23; everything went smoothly and we had made several notifications to the various communities about this minor change and more detailed information can be found on MediaWiki. [9] [10] * Stas improved field mapping for nginx logstash by adding a few field types [11] * Trey finished up a Language Analysis Morphological Library Research Spike and identified 6 languages that will be researched more deeply in the coming weeks [12]

=== Analysis === * Mikhail attended the Mobile App team's offsite last week and learned quite a bit about their processes and gave suggestions on how Analysis can help in the future.

=== Portal === * Jan fixed a minor issue with the dwell-time impact of `touch-action: manipulation;` on the portal [13] * We had help from the community on a minor bug with a licensing link in the footer, the code has been merged and will be in production with our next portal update, tentatively scheduled for Monday, Oct 30. [14] * After chatting with RelEng earlier this week, we decided to not do some of the work we had thought we needed to do in order to automate the portal updates. [15] * The name for Northern Sami needed to be changed on the portal from "Sámegiella" to "Davvisámegiella" - this change was done in translatewiki and will be in production with the next portal update, tentatively scheduled for Monday, Oct 30. [16]

=== Maps === * The maps team and various others have been chiming in on the best way to deploy meddo as part of tilerator-deploy—Gehel has gone ahead with a few patches that will replace direct dependencies with Kartotherian dependency and adding meddo and ClearTables as deployment dependencies, but more conversations might be needed.
