I'm not sure where to talk about this, but here a try :-)
Xapian is integrated in 1.8.x to search almost all entities in the system.
Are there plans to support the same in 2.x ?
Is there any other different approach about search in 2.x ?
I originally worked on xapian integration for 1.8.x, and I want to do the same for 2.x ;-), but I still could not try 2.x :-p. So first, is there interest on that?
