This is the weekly update for the week starting 2017-07-17

==Highlights== Highlights
 * Quarterly Review check-in's were presented this week (links forthcoming).

==Discussions== Discussions
 * Had a good conversation on how we want to do an upcoming A/B test to have search results interleaved
 * Also had a really interesting conversation on how we should move forward with metrics and KPIs for the Search Platform and Discovery.

Search

 * After extensive help and feedback from the Japanese Wikipedia community, we decided not to deploy the new Japanese language analyzer. (T166731)
 * After testing and analysis, we are not going to deploy the Vietnamese language analyzer (task T170423)
 * Did some quick analysis of the RelForge impact of initial learning-to-rank model
 * Completed a high level task of organizing necessary adjustments to the ElasticsSearch learning-to-rank plugin
 * Updated the Wikidata code to take advantage of nested fields noop script
 * Analyzing the new Kuromoji Japanese language analyzer is done, just waiting to merge the updated configuration
 * A/B test for the new search results Explore Similar feature continues after fixing a minor bug
 * Fixed a mapping bug when using text for 'did you mean' suggestions
 * Updated the 'cirrussearch-explore-similar-languages-none' message to be more meaningful (will be deployed the week of July 25, 2017)

Analysis

 * To track sister project search feature, the Search Metrics dashboard now shows traffic to various Wikimedia projects from Wikipedia search results pages: https://discovery.wmflabs.org/metrics/#sister_search_traffic
 * We found what lowered full-text search PaulScores – it was a change of event logging sampling rates (decreasing enwiki and increasing all other wikis). (T168466)
 * Investigated the seemingly odd statistic of mobile web having the highest usage of the sister project snippets in the search results page; conclusion: nothing to worry about, everything is being logged correctly.

Portal

 * The Wikipedia portal stats and translations  were updated on July 18, 2017

Maps

 * A usage policy was recently changed for the relief data layer that we use in maps to now require an API key; a key was procured and Max S helped us get it into production. This only effected maps on Wikivoyage.
