Hi,

I've just tried your plugin with the latest nightly build of solr.

I got the foolowing exception:

after investigations, it seems that DocIdSet is deprecated and removed as said here:

http://lucene.apache.org/java/2_4_0/api/org/apache/lucene/search/Filter.html

Any idea to solve the problem?

> BitwiseQueryParserPlugin is a org.apache.solr.search.QParserPlugin that allows 
> users to filter the documents returned from a query
> by performing bitwise operations between a particular integer field in the index
> and the specified value.
> This Solr plugin is based on the BitwiseFilter in LUCENE-2460
> See https://issues.apache.org/jira/browse/LUCENE-2460 for more details
> This is the syntax for searching in Solr:
> http://localhost:8983/path/to/solr/select/?q={!bitwise field=fieldname op=OPERATION_NAME source=sourcevalue negate=boolean}remainder of query
> Example :
> http://localhost:8983/solr/bitwise/select/?q={!bitwise field=user_permissions op=AND source=3 negate=true}state:FL
> The negate parameter is optional
> The field parameter is the name of the integer field
> The op parameter is the name of the operation; one of {AND, OR, XOR}
> The source parameter is the specified integer value
> The negate parameter is a boolean indicating whether or not to negate the results of the bitwise operation
> To test out this plugin, simply copy the jar file containing the plugin classes into your $SOLR_HOME/lib directory and then
> add the following to your solrconfig.xml file after the dismax request handler:
> <queryParser name="bitwise" class="org.apache.solr.bitwise.BitwiseQueryParserPlugin" basedOn="dismax" />
> Restart your servlet container.
