You could use Query.extractTerms(..) and then search for possible
matches in the field term vector (requires stored TV).

Isn't maxClause count just a "best practice" limit to asure that
performance doesn't decrease silently if big queries occur?
Performance and memory consumption should depend on how many clauses
are really used / number of matching documents
I think that there is no (significant) difference in memor

Sorry for pushing this thing.
Would it be possible to add the demanded constructor or would it break
anything of lucenes logic?

This is because matches in short fields (few terms) als typically more
pregnant, than matches in long fields (much terms).
Imagine the case with two fields named "title" and "content"
representing the title and the content of books.
If you match three search terms in a five terms title this is a b
Hey out there,
in lucene it's not possible to create a Field based on a TokenStream
AND supply a stored value.
Is there a reason why a Field constructor in the form of
public Field(String name, TokenStream tokenStream, String storedValue)
does not exist?
I am using trees of TeeSinkTokenFilter

Erick, I'm not sure if I understand you right.
What do you mean by "spinning through all the terms on a field".
It would be an option to load all unique terms of a field by using TermEnum.
Than use TermDocs to get the docs to those terms.
The rest of docs doesn't contain a term and so you know, th
Hi,
I'm using Lucene 2.9.1 patched with
http://issues.apache.org/jira/browse/LUCENE-1260
For some special reason I need to find all documents which contain at
least 1 term in a certain field.
This works by iterating the norms array only as long as the field
exists on every document.
For documents
Maybe the command line argument "-verbose:gc output" would help to
determine if GC is running.
But you are right - a profiler would be the best way.

Hello,
sorry for causing inconvenience.
It was my mistake and i wasn't able to reproduce it completely this morning.
My testcase was a little to complex and there were two or three bugs /
false assumptions which made it look to me like i explained above.

Hello everyone,
I'm a little bit confused about the docBase parameter of
Collector.setNextReader.
Imagine the following:
- Create new Index
- Index 5 docs
- Call IndexWriter.commit()
- Index 7 docs
- Call IndexWriter.commit()
- close Writer
Now I have a 2-segment index right?
I have

thanks for your reply.

Looks like a solution for that problem.
Why wasn't it applied to lucene?

Hi,
i've got a problem concerning encoding of norms.
I want to use int values (0-255) instead of float interpreted bytes.

getNormDecoder.
