Are you absolutely, 100% sure that the -2 token has actually made it
into your index?
As a VERY basic way to check this try something like this:
import org.apache.lucene.index.IndexReader;
import org.apache.lucene.index.TermEnum;
public class IndexTerms {
public static void main(String[] args) {
try {
IndexReader ir = IndexReader.open("C:/Search/index/index");
TermEnum te = ir.terms();
while (te.next()) {
System.out.println(te.term().text());
}
}
catch (Exception e) {;}
}
}
Then look through the output, verifying that the tokens you are
expecting to exist in your index, actually do.
I have a feeling that whatever analyzer you are using is dropping the
"-" from the front of your "-2" at indexing time, and if so it can
sometimes be pretty hard to tell via Luke.
Hope this helps,

whitespace analyzer will tokenize on white space irrespective of quotes. Use

I'm using Luke to find the right combination of quotes,\'s and
analyzers.
No combination can produce a positive result for "-2 String" for the
field 'type'. (any -<number> <String>)
type: 0 -2 Word
analyzer:
query -> rewritten = result
default field is 'type'.
WhitespaceAnalyzer:
\"-2 ConfigurationFile\" -> type:"-2 type:ConfigurationFile" = NO
-2 ConfigurationFile -> -type:2 type:ConfigurationFile = NO
\-2 ConfigurationFile -> type:-2 type:ConfigurationFile = NO
"\-2 ConfigurationFile" -> type:"-2 ConfigurationFile" = NO (thought
this one would work).
Same results for the other analyzers more or less.
Weird.

Hi, While constructing the query give the query string in quotes.
eg: query = queryparser.parse("\"-2 word\"");

I'm hoping to do this with a simple query string, but not sure if its
possible. I'll try your suggestion though as a workaround.
Thanks!!

Hi,
This might be a dumb question, but I have a simple field like this
field: 0 -2 Word
that is indexed,tokenized and stored. I've tried various ways in
Lucene
(using Luke) to search for "-2 Word" and none of them work, the
query
is
re-written improperly. I escaped the -2 to "\-2 Word" and it still
doesn't work. I've used all the analyzers.
What's the trick here?
Thanks,
Darren
