Uwe Schindler commented on LUCENE-4282:
---------------------------------------
This is caused by the rewrite method not FuzzyQuery itsself. The rewrite mode
uses an internal priority queue, where it collects all terms from the index,
that match the levensthein distance. If there are more terms available, some
are dropped. This depends on their distance and other factors. If you want to
use a larger PQ, create a separate instance of the TopTermsRewriteMethod,
giving a queue size.
> Automaton Fuzzy Query doesn't deliver all results

> Project: Lucene - Core
> Issue Type: Bug
> Components: core/search
> Affects Versions: 4.0-ALPHA
> Reporter: Johannes Christen
> Labels: newbie
>
> Having a small index with n documents where each document has one of the
> following terms:
> WEBER, WEBE, WEB, WBR, WE, (and some more)
> The new FuzzyQuery (Automaton) with maxEdits=2 only delivers the expected
> terms WEBER and WEBE in the rewritten query. The expected terms WEB and WBR
> which have an edit distance of 2 as well are missing.
