Hi Tom,
You are using a SimpleAnalyzer while indexing which will do some transformation
to your string before indexing. If you are using analyzer which does
transformation to the words during indexing you should use the same or similar
analyzer during querying as well.
Try the same with KeywordAnalyzer instead of SimpleAnalyzer it will work
because keyword analyzer stores as keywords without removing any letters. So it
will match.

Subject: Index and search terms containing character "-"
Hi,
I have a problem using TermQuery and FuzzyQuery for terms containing the
character "-". Considering I've indexed "jack" and "jack-bauer" as 2 tokenized
captions, I get no result when searching for "jack-bauer". Moreover, "jack"
with a TermQuery returns the two captions.
What should I do to get "jack-bauer" with new TermQuery("jack-bauer") ?
A full test case is given below.
Thanks,
Tom
