if you need the number of docs in which a given term appears you can use the
method docfreq
http://jakarta.apache.org/lucene/docs/api/org/apache/lucene/index/IndexReader.html#docFreq(org.apache.lucene.index.Term)
otherwise you can use

I submitted a patch a few days ago (see

Has someone tested this feature? Is there a reason not to commit it?

DocumentWriter is typically created with the

So getDirectory() should return this ramDirectory in order to work,

Of course I'd be pleased to make a draft of the javadoc and a patch file.

s the best way to set up this value in IndexWriter? Maybe we could
limit to a few possible values like :
DEFAULT = 128
AVERAGE = 64
HIGH = 32
in order to avoid too low settings.
Any comments or suggestions? Can anyone give feedback on this?

In my case it works perfectly. As we generate multilingual and semantic

There's a new release of limo available !
This new version :
- includes lucene-1.3-final.jar
- fixes a bug with index loading
- detects when index changes and auto refreshes the information (as proposed

- uses css for easier customisation (as proposed by E Hatcher)
- escapes HTML

Here is a use case :
- my Lucene application is running under W2K
- I have (just) a gigabyte RAM
- my index is quite big, let's say 1.7 Gb (with a .tis of 31Mb an a .tii of
479 Kb)
Using RAMDirectory is impossible, FSDirectory works but is quite slow.
Could it be possible to create a custom Direc

BTW modifications are to be made in the org.apache.lucene.store.InputStream
class, not in Directory.
Has anybody else tried it? Do you find similar results? What does it bring
on a bigger index?

No, TermDocs operates only on Terms, not on PhraseQueries. A PhraseQuery is
a query and is not stored in an index.

I observed a change in the ordering of the results since I moved from 1.2 to

Another feature could be the ability to retrieve the number of occurences
not only for a term

The only difference in my functionality is that query.getTerms() returns
