Hi all,
Let's say that I have in my index the value "One Two Three" for field 'A'.
I'm using a custom analyzer that is described in the forwarded message.
My Search query is built like this:
QueryParser parser = new QueryParser(LABEL_FIELD, ANALYZER);
Query query = parser.parse(LABEL_FIELD + ":" + searchQuery);
So when I search for
1) On*
I get a match with "One Two Three"
But when I search for
2) One Tw*
I get no matches. query.toString outputs:
3) label:One label:Tw*
which is obviously wrong. If I surround my search strng with ":
4) "One Tw*"
query.toString outputs what I was expecting:
5) label:One Tw*
but I still get no matches, and now even the first search (1) doesn't work.
Looking through the API I found this MultiPhraseQuery, but the doc was very
confusing. I tried it out but with no luck (I think I did it wrong). In any
case, is MultiPhraseQuery what I'm looking for? If it is, how should I use
the MultiPhraseQuery class?
Thanks,
Andre

Just to add to that, as I said before, in my case, I found more useful not
to use UN_Tokenized. Instead, I used Tokenized with a custom analyzer that
uses the KeywordTokenizer (entire input as only one token) with the
LowerCaseFilter: This way I get the best of both worlds.
public class KeywordLowerAnalyzer extends Analyzer {
public KeywordLowerAnalyzer() {
}
public TokenStream tokenStream(String fieldName, Reader reader) {
TokenStream result = new KeywordTokenizer(reader);
result = new LowerCaseFilter(result);
return result;
}
}
