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
