Requires a lot more complexity to the code though..Couldn't Dovecot just search the index with each single word (as it does now without OR), and then merge the results, filtering out double UIDs? This is probably not the most efficient way to solve this, but it would be definitely *much* faster than not using the indexes at all - and doesn'tsound too complex to me.
It would be nice to allow the FTS backend to handle as much of this as possible. For example with Lucene you could merge several AND/ORs into a single query. But maybe it's not worth the trouble to do all that complexity. But at least the OR-only search could be a special case where all the words are sent to backend. In a mixed AND/OR query then it could do several queries and merge the results. And sure, it's not *that* complex but it'll require a few hours of work.
Are there any other not-yet-implemented SEARCH features that don't workwith the FTS plugin?
Shouldn't be. Or perhaps things related to header searches could be better optimized.
