Hi Erik and all, I'm still trying to solve this issue and I like to know how others might have solved it in their client. I can't modify Solr / Lucene code and I'm using Solr 1.2.
What I have done is simple. Given a user input, I break it into words and then analyze each word. Any word contains wildcards (* Or ?) I lowercase it. While the logic is simple, I'm not comfortable with it because the word-breaker isn't based on the analyzer in use by Lucene. In my case, I can't tell which analyzer is used. So my question is, did you run into this problem, if so, how did you workaround it? That is, is breaking on generic whitespaces (independent of the analyzer in use) "good enough"?
