Sorry for the delayed response...
Thanks, thats what I thought. In my case, the schema of each index
would be slightly different, so I would want to run a PrefixQuery
against each index (all fields in each index) using the same query
text. Maybe I would be able to take the results from each inde
Have you looked at TermFreqVector?

Yes on all counts. Lucene doesn't modify query objects, so they are
save for reuse among multiple threads.

Hi,
Can anybody confirm whether MatchAllDocsQuery can be used as an
immutable singletone? By this I mean creating a single instance and
sharing it whenever I need to either use it on its own or in
cojunction with other queries put into a BooleanQuery; to result all
documents in a search result. Ca
Hi,
If I index a document (single document) in Lucene, then how can I get the
term frequencies (even the first and second highest occuring terms) of that
document? Is there any class/method to do taht? If anybody knows, pls. help
me.
Thanks

Hi Anshum & Erick,
As you have mentioned, I used SnowballAnalyzer for stemming purposes. It
worked nicely. Thnks a lot for your guidence.

One way would be to identify the most recently added document, save
that info somewhere, and close the IndexWriter as normal. Then, when
you restart the indexing of the file, skip ahead and start from the
last indexed document. Or skip the identify/save bit if your
indexing app already has code
Hi all,
Imagine a situation: Lucene started indexing a huge file, and just after
this user demands the application to be shut down immediately. What would be
the recommended way of doing this, so that application shuts down within
seconds, but with least possible damage to the index?

Your usage (searching for old doc & updating it, to add new fields) is fine.
But: what memory usage do you see if you open a searcher, and search
for all docs, but don't open an IndexWriter? We need to tease apart
the IndexReader vs IndexWriter memory usage you are seeing. Also, can
