Delete documents base on more than one condition?

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,

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 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 .
