------------------------------------
Hi Israel, interesting stuff!
There's always many different ways to approach... but I had previously planned
to add these functions (and,or,not,xor) to the function query suit. We'd also
need something to filter results (since function queries normally return a
value for every document).
So maybe something like
{code}
fq={!func}filter(and(field1,xor(0xdeadbeef,field3)))
or
fq={!funcfilter}and(field1,xor(0xdeadbeef,field3))
{code}

> Key: SOLR-1913
> URL: https://issues.apache.org/jira/browse/SOLR-1913
> Project: Solr
> Issue Type: New Feature
> Components: search
> Reporter: Israel Ekpo
> Fix For: 1.4, 1.5, 1.6, 3.1, 4.0

> 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.
