Grant Ingersoll commented on LUCENE-950:
----------------------------------------
Hmmm, this isn't really an error (see
http://lucene.zones.apache.org:8080/hudson/job/Lucene-Nightly/javadoc/org/apache/lucene/search/FuzzyQuery.html)
but I can also see that the QueryParser Syntax
(http://lucene.apache.org/java/docs/queryparsersyntax.html) doesn't explicitly
state that 1 is excluded, even if the Javadocs do. It says:
"Starting with Lucene 1.9 an additional (optional) parameter can specify
the required similarity. The value is between 0 and 1, with a value closer to 1
only terms with a higher similarity will be matched."
I could see that a patch saying something like "The value is between 0 and 1
(but not including 1), with a value closer ..." would be appropriate.
So, I will leave this open for now, even though I feel the QueryParser and
FuzzyQuery are operating correctly.
