Re: [Wikidata] Wikidata fulltext search prototype

Hi! Thanks for your kind words. You can track it here: https://phabricator.wikimedia.org/T125500 and associated tasks like this one: https://phabricator.wikimedia.org/T178851 which contain links to the patches. The search runs on the same ElasticSearch we use for search on other sites, but the prototype has specific code to deal with Wikidata specific data structure and the fact that it is, unlike most other Wikimedia sites, multilingual by design. The rankings are hand-tuned now and kind of hard to read right now (we're working on improving this), they are contained here: https://phabricator.wikimedia.org/diffusion/EWBA/browse/master/repo/config/ and specific functions we're using here: https://phabricator.wikimedia.org/diffusion/EWBA/browse/master/repo/config/… Basically it's a combination of match score (how well the string matches the query), incoming link count, sitelink count and special boosts like demoting the disambiguation pages. -- Stas Malyshev smalyshev(a)wikimedia.org
