Hi
Is it possible to delete a set of documents where they match certain
conditions? I would like to delete a set of articles that belong to a
given user within a category.
Thanks,

Hi Rajashekhar,
yet it is possible . You can form a Boolean Query which will match the
documents as per your required conditions . Then you can delete by the
respective document ids by instantiating a indexReader.
You can refer to Book Lucene in Action 2nd Edition for more details .
Thanks,

Or, easier, just pass the Query identifying the docs to
IndexWriter.deleteDocuments(Query query). There are variants that
take multiple queries and single or multiple terms. See the javadocs.
You can't delete docs via IndexReader any more.

Hi,
I have a problem understanding and applying the BitSets concept in
Lucene 4.0. Unfortunately, there does not seem to be a lot of
documentation about the topic.
The general task is to extract Spans matching a SpanQuery which works
with the following snippet:
for (AtomicReaderContext atomic : r
Hi all,
I am new with Lucene.
I try to understand how can I find the term position.
I use following code to index documents:
...
IndexWriter writer = new IndexWriter(mIndexDir, mIwc);
FileInputStream fis;
fis = new FileInputStream(file);
Document doc
terms = fileds.terms(...);
termsEnum = terms.iterator(null);
termsEnum.seekExat(...);
docsAndPositionsEnum docsPosEnum = termsEnum.docsAndPositions(...);
You can get the information in "docsPosEnum".

If you are using lucene 4.0 and afford to compress your document dataset while
indexing, it will be a huge savings in terms of disk space and also in IO
(resulting in indexing throughput).
In our case, it has helped us a lot as compressed data size was roughly 3 times
less than of original doc
