negative filter queries
-----------------------
Key: SOLR-80
URL: http://issues.apache.org/jira/browse/SOLR-80
Project: Solr
Issue Type: New Feature
Components: search
Reporter: Yonik Seeley
There is a need for negative filter queries to avoid long filter generation
times and large caching requirements.
Currently, if someone wants to filter out a small number of documents, they
must specify the complete set of documents to express those negative conditions
against.
q=foo&fq=id:[* TO *] -id:101
In this example, to filter out a single document, the complete set of documents
(minus one) is generated, and a large bitset is cached. You could also add the
restriction to the main query, but that doesn't work with the dismax handler
which doesn't have a facility for this.
