Not sure what others think, or how many will be at Wikimania.
I know that I haven't done enough playing with Cirrus Search functionality, and I am not sure what those WSes (other than enWS) have done to have a more sophisticated offering to users. Might be useful if we could find half an hour during WM2014 to throw some ideas around, and maybe whiteboard what we would like CirrusSearch to do for us (if anything).
After reading some of the wikitech-ambassador email today, I know that I stumbled over some documentation/thought boxes at http://git.wikimedia.org/tree/mediawiki%2Fextensions%2FCirrusSearch.git/mast... which while providing detail, doesn't gel for how we might implement things in a better way.
