Sphinx reindex RT index

Question

I have sphinx RT index, but i forgot add morphology when start insert records :( Can i rebuild RT index without lost data? My config:

index track {
    type = rt
    path = /var/...
    other options...
}

searchd {
    listen = 127.0.0.1:9306:mysql41
    workers = threads
    other options...
}

I want add morphology = stemenru to index section, but command indexer --all --rotate has not results.

Answer 1

You will have to delete the index and start again.

Can't change morphology after the index has been created (because it changes how words are stored)

... indexer plays no role in RT indexes. RT indexes are entirely managed by searchd.
