what are these 3 used for? filterProfanities is a boolean now so these shouldn't
be required.

Done.

should this default to 'builtin:dictation' as extensions aren't always going to
be built for searching stuff? just something to think about and talk with more
people

[Leandro Graciá Gil, 2011/10/09 10:29:21]

Yes, you got a point. That's something we should probably discuss.
