Re: [jira] [Commented] (LUCENENET-486) Wildcard queries are not analyzed
Björn Kremer 2012-04-20, 07:10
Hello,

unfortunaly I can't add a file to this closed issue. I have uploaded my
workaround here: http://pastebin.com/B1n5wJds (Diff of function
'GetPrefixQuery'). I'm not very familiar with the lucene code. So I only
invoke 'GetFieldQuery' to analyze the string. Maybe there is a better
solution. But it works for my purpose.

Thank You
Björn
