Subject Re: How to recover from "Error opening new searcher" when machine crashed while indexing
Date Wed, 01 May 2013 11:14:32 GMT
Alas I think CheckIndex can't do much here: there is no segments file,
so you'll have to reindex from scratch.

Just to check: did you ever called commit while building the index
before the machine crashed?
