      Description

      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.
