The problem is not actually any issue with FuzzyQuery, it is the Query.combine() with any Boolean rewrite... including AUTO as i mentioned earlier in this thread! AUTO starts out building a boolean rewrite... if certain magical conditions are hit (exceeds certain number of terms, or certain DF), then it switches over to a Filter. So, for example AUTO proclaims it will never hit boolean maxclauses exceeded exception, but it can (imagine multisearcher with 5 searchers, it expands to 250 each, but then after combine() this is > 1024). In my opinion Query.combine() is completely broken, and i don't see how it can really be fixed to work with arbitrary query structures since a query might rewrite() differently on the different searchers. --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
