Query Parser custom analyzer question
I have a custom Analyzer which performs normalization on all of the
terms as they pass through.
It does normalization like the following:
trees -> tree
Sometimes my normalizer returns multiple words for a normalization - for
example:
leaves -> leaf leave
The second and all subsequent terms have the position increment set to 0.
The problem I am having now is that the QueryParser seems to ignore the
positionIncrement values.
If I create a QueryParser with my normalizing analyzer, and ask it to
parse the following (default field of 'body'):
'something about leaves' - the query it generates is: 'body:something
body:about body:"leaf leave"'
which does not find results, due to the double quotes.
I would have expected: 'body:something body:about body:leaf body:leave'
Is there any way I can fix this? It is a bug? Or just a mis-use and/or
unsupported use case of the Query Parser?
Thanks,
Dan

You need to get it from SVN and then build it yourself.

In my opinion the code is ready, it's just that someone needs to start with
the release process (which is not as trivial as it may sound).

Cool - is there a daily build somewhere, or do I have to roll my own? I
couldn't find a daily build or a 1.9 alpha, beta, etc. on the site.
Any idea when 1.9 might be released, even as an alpha? The dates in the
Lucene2Whiteboard on the wiki no longer look realistic (unless the 1.9
release is going to happen at the same time as the 2.0 release - which I
could understand, if the 2.0 will only differ by removing all of the
depreciated methods.
Thanks,
Dan

Correct handling of multiple terms per position was only added to SVN, it's
not part of Lucene 1.4.3.
