Subject [jira] [Created] (LUCENE-4024) FuzzyQuery should never do edit distance > 3
Date Thu, 26 Apr 2012 12:54:17 GMT
Michael McCandless created LUCENE-4024:
------------------------------------------

             Summary: FuzzyQuery should never do edit distance > 3
                 Key: LUCENE-4024
                 URL: https://issues.apache.org/jira/browse/LUCENE-4024
             Project: Lucene - Java
          Issue Type: Improvement
            Reporter: Michael McCandless
             Fix For: 4.0


Edit distance 1 and 2 are now very very fast compared to 3.x (100X-200X faster) ... but edit
distance 3 will fallback to the super-slow scan all terms in 3.x, which is not graceful degradation.

Not sure how to fix it ... mabye we have a SlowFuzzyQuery?  And FuzzyQuery throws exc if you
try to ask it to be slow?  Or, we add boolean (off by default) that you must turn on to allow
slow one..?
