[Dovecot] Squat Question!

Hello folks,

I use dovecot squat for indexing.

I use to have

fts_squat = partial=4 full=4

But i change to fts_squat = partial=4 full=8

My question is, do i need to delete older indexes to have it consistenly, or dovecot is able "update" the indexes or it sees that it is broken and rebuild it all?

Other question, is there an comand line to update the indexes ?

Thanks a lot!
