Hi all,
If you haven't been following along with development, we're working on replacing MWSearch/lsearchd with CirrusSearch (powered by Elasticsearch). Nik and I been working on this for the last several weeks and now it's ready for wider testing outside of labs.
This is invitation for you to play with some totally alpha software and report all kinds of bugs you may find. So hop on over to https://test2.wikipedia.organd mess around with Special:Search and the API's list search and prefix search.
When testing this, it's useful to compare results from the old and new engines. I added some query parameters that let you toggle between them. Just add srbackend=LuceneSearch|CirrusSearch to force one or the other.
All bugs can be filed in BZ under the CirrusSearch component[0]. Depending on how things go, we'd like to roll this out for mw.org on the 28th. Happy bug hunting :D
-Chad
