Guten Tag, This is the Discovery weekly update for the week of 21 August. As always, feedback and questions are welcome.

== Discussions ==

=== Search === * Daniel added the ability to create derivative features in the learning to rank plugin [0] * Erik also built an oozie job to collect click data for the learn to rank plugin [1] * Jan fixed a minor UI bug with the sister project snippet display for when TextCat determines that a user might be searching in a different language [2] * Trey wrote up an analysis of unexpected behavior when searching for Japanese words on English Wiktionary. Input from Japanese speakers and others who search for Japanese on wikis in other languages is welcome! [3]

Some leftovers: * Last week Trey disabled the indexing of punctuation on Chinese Wikipedia. [4] The new language analyzer does a lot of good things, but indexing punctuation isn't helpful and wastes a lot of space in the index. We still need to re-index the Chinese wikis to make this active. [5]

=== Analysis === * Mikhail added map layer metrics to event logging for mapframe [6] * Chelsy has the draft analysis ready for the A/B explore similar test [7] [8] * Mikhail and Guillaume have been working on fixing the issue with metrics not being available (due to a variety of reasons); it's not completely fixed yet, but we're working on it [9]

=== Portal === * The Wikiversity logo was updated [10] * The portal stats and translations were updated on Aug 24, 2017 [11] [12]

=== Maps === * TheDJ (community volunteer) migrated Kartographer to Leaflet 1.x as part of the Montreal Hackathon 2017 [13]

== Did you know? == * You can activate ''all'' the possible search result options (spelling correct, offer to create the page, a local result, sister project results, and cross-language results) with the query ''max planck wissenschaftliche sich night'' on English Wikipedia—it's too much search awesomeness for one page to contain! And it's why we need to figure out a general framework for dealing with everything before adding more options, like "wrong keyboard" detection [14] [15] * Everyone is encouraged to upload pictures of the solar eclipse from Aug 21, 2017 to Wikimedia Commons. If you have pictures, share; if you want to see some great pictures, there are already many there! [16] [17]
