You can change the grammer and regenerate QUeryParser.java, but there is
no progromatic mechanism for this.

Hello again,
If I wanted to do this programmatically, how would I do this (retrieve a
list of all terms in a field for a specific document - better if it was in
alphabettic order and with frequency data)?
Thanks,
Itamar.

Thanks for the advice Chris. What I am working on now is extracting the
matching phrases. The current code for MultiPhraseQuery and SpanQueries
just return all matching terms, not matching phrases. I implemented some
code matching up the TermPositions, but this is pretty slow. Is there any

Ah ok. I tested it. Creating an IndexWriter on an index with 10.000 docs
(about 15 MB) takes about 200 ms.
This is a very cheap operation for me ;)
I only saw the many calls in init() which reads files and so on and
therefore I to
I don't think creating an IndexWriter is very expensive at all.
Especially compared to creating an IndexReader, for example.

Then, you can call close() to commit the changes to the index, or

As I understand the docs, the index will get rolled back to the

Hi all,
I have the behaviour that when I search with Luke (version 0.7.1, Lucene
version 2.2.0) inside an arbritray field, the QueryParser creates a PhraseQuery
