 * Upgrade Elasticsearch to 0.90.4 - Sep 18
 * Upgrade Elasticsearch to 0.90.7 - November 18
 * Install new Elasticsearch servers and decommission testsearch100X - November 18
 * Upgrade Elasticsearch to 0.90.9 - January 2
 * Upgrade Elasticsearch to 0.90.10 - January 14
 * Upgrade Elasticsearch to 1.x - Mid February?
 * This one is a pain because we have to take down the whole Elasticsearch cluster during the upgrade. Either we build a parallel cluster or we fall back to lsearchd.

Solr vs Elasticsearch
We spent some time looking at search systems we could use and it became pretty apparent that the thought leaders in the open source world for search are Solr and Elasticsearch. We spent a few weeks with each and decided to build on Elasticsearch because of its wonderful suggester, easily composable queries and good documentation. We are also happy with the process of submitting changes upstream to Elasticsearch.

Core Search
We're working feverishly on CirrusSearch and we're deploying it to wikis on a volunteer basis. We're actively looking for new volunteers so if you want in email neverett@wikimedia.org.

GeoData
We've just started looking at how to move GeoData to Elasticsearch. For now, it'll remain in Solr with plans to migrate it to Elasticsearch when time permits. Some considerations:

The index is relatively small (so no need to make it distributed), but requires a lot of computational power to work with. Full-text search is not currently used. Currently, data from all the wikis is stored in the same core, in the future we will need to split data to many cores (the puppet changes for using multiple cores with shared configuration/schema are here, needs more work).
 * Load expectations: unclear, but will be high if we start using it heavily e.g. for maps display.
 * Backups: not really needed - if master is down just switch to a slave. If all servers are down, reindexing from scratch is quick.
 * Note: because GeoData's schema is very stripped-down, /admin/ping doesn't work - should be remembered if someone wants to rewrite the current monitoring.

Translation Memory

Search Weighting Ideas
Some things that could be factored into search results, in rough proposed grouping order:

(+) positive impact on default ranking (-) negative impact on default ranking

Relationship

 * In-article searches (when I'm reading an article, I want to search within it) (+)
 * GeoLoc of user when searching (+)
 * Articles nearness (geographically) to current article (+)
 * Articles linked from current page (+)
 * Wikidata related items (+)
 * Categories on articles (+)

Relevance

 * Article "meshiness" (number of articles that link to article, number of articles that article links to) (+)
 * External search referrer terms saved into article metadata (not a thing yet) (+)
 * Article importance (per wikiprojects) (+) (-)
 * Recency of last edit (+) (-)
 * Article recency (creation) (+)
 * Matches in title, headings, body text, alternate text, references (weighted differently) (+) (-)
 * Other wiki search results
 * Is this a weighting thing, or a content type thing (e.g. if it has related results on other wikis it's ranked higher)?

Quality

 * Notability of an article (i.e. featured) (+)
 * Article quality (per wikiprojects) (+) (-)
 * Content with article issue templates (-)
 * Calls to action (number of article issues, missing images, etc.) (-)
 * Stub status (-)

Aggregate User behavior

 * Top searches in the last hour/day/week (+)
 * Search terms that were followed vs unfollowed (+) (-)
 * Recent pages arrived at via external search (+)

General Search Behaviors

 * When zero results are found for exact match but "did you mean" is shown, show special header with did you mean note and create article note, but show did you mean results instead.
 * In full text search show exact text page title matches in alternate visual appearance

Research

 * Show floating right side microsurvey widget to rate search results
 * Allow users to up and down vote results as relevant to inform weighting hypothesis
 * Analyze search/followed link pair
 * Run microsurvey "is this what you were looking for" on results page?
 * Can we determine if it was what they were looking for without asking?
 * amount of page viewed
 * back to results rather than following link on page or bounce
