Description

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.
