Another week, another update from the Search Platform team. This one
is for the week starting 2018-04-09.
As always, feedback and questions welcome.
== Discussions ==
=== Search ===
* New search code fully deployed & enabled on Wikidata.
==Events and News ==
* Erik and Trey went to the "OpenSource Connections Haystack Search
Relevance Conference" and "Tom Tom Founders Festival Machine Learning
Conference", which were back-to-back in Charlottesville, VA. Erik
presented on how we use clickstream information to create training
data for our learning to rank models at Haystack.  Trey wrote up
trip notes—with lots of links—on MediaWiki. 
== Other Noteworthy Stuff ==
* Fix for CirrusSearchCheckerJob errors rolled out. 
* Stas implemented indexing Lexemes & Forms for WikibaseLexeme extension. 
== Did you know? ==
*The English verb "to be" is kind of weird—the infinitive "be" and
participles "being, been" start with "b-", while the preterite forms
"was, were" start with "w-", and the present forms "am, is,
with vowels. The conjugations originally come from three or four
different verbs! Why "three or four"? Wiktionary disagrees with itself
a bit, listing four on the etymology of "is"  and three on the
etymology of "be".  The conflation goes back at least to
Proto-Germanic,  so German is similarly weird.  Dutch has a
greatly simplified paradigm, but still shows some trace of the
multiple sources.  Other languages, including ASL, Arabic, Bengali,
Hawaiian, Hebrew, Indonesian, Japanese, Russian, Turkish, and
Ukrainian at least partly avoid this mess by having a zero copula.
 For search on-wiki, we deal with this problem in part with
stemming  and stop words.
