Have a look at the SpanQuery (starting at page 161 in LIA or in the
javadocs). I also have some info in my ApacheCon talk at http://
www.cnlp.org/presentations/slides/AdvancedLuceneEU.pdf and http://
www.cnlp.org/apachecon2005
Incidentally, the SpanQuery functionality does not require
TermVectors, so if you don't need them otherwise, you would get a
smaller index size.
Cheers,
Grant

Hi all,
I am new to Lucene and I have been reading the book "Lucene In
Action",
here is my question:
When searching for a word through an index is there any way to know in
which positions (may be more than one) of each document that word was
found?
The index is constructed in the following way:
---------------------
IndexWriter writer = new IndexWriter("/path/to/the/index/dir",
new StandardAnalyzer(), true);
writer.setUseCompoundFile(false);
Document doc = new Document();
doc.add(new Field("contents",
new FileReader(f),Field.TermVector.WITH_POSITIONS_OFFSETS));
doc.add(new Field("filename", f.getCanonicalPath(), Field.Store.YES,
Field.Index.NO_NORMS));
writer.addDocument(doc);
.....
--------------------
Thanks in advance
--
Felipe.
