Subject Re: [jira] Updated: (SOLR-1913) QParserPlugin plugin for Search Results Filtering Based on Bitwise Operations on Integer Fields
Date Sun, 16 May 2010 04:12:21 GMT
Hi Pradeep,

There are a couple of uses cases I can think of in my own applications.

Also, inquiries like these made me believe there are also others that may
have similar needs:

http://lucene.472066.n3.nabble.com/bitwise-comparer-td485697.html
http://lucene.472066.n3.nabble.com/Query-with-bitwise-operation-td495193.html
http://lucene.472066.n3.nabble.com/Solr-and-bitwise-comparaison-td504367.html
http://lucene.472066.n3.nabble.com/Best-way-to-handle-bitfields-in-solr-td473621.html

I hope that answers your question.
