Folks,

I raised this issue a while back but it went unanswered so I'm trying again.

Anyhow, FuzzyTermEnum.java appears to have two problems -

1) FuzzyTermEnum searches are case sensitive. Presumably this is not as 
designed? See bug #18014 for a candidate patch.
2) The "Query Syntax" page on the website states in the "Fuzzy Searches" 
section, that:
 
     "Terms found by the fuzzy search will automatically get a boost 
factor of 0.2"

    I've found this not to be the case. In my previous email ( 
http://www.mail-archive.com/lucene-dev@jakarta.apache.org/msg02819.html 
) I documented a test case for this. Fuzzy matches appear for me ahead 
of some exact matches in some cases. As this is not as clear cut a bug 
as the case sensitivity issue, I didn't post this as a bug.


any feedback you have would be much appreciated.

Thanks,
--Cormac Twomey
