Subject Re: [jira] [Commented] (SOLR-2580) Create a new Search Component to alter queries based on business rules.
Date Wed, 08 Jun 2011 23:05:18 GMT
Actually I applied business rules using dismax , using a layer to rewrite
the query so that it meets user specific preferences ,so search results for
a user not the same for another user  and we can boost queries based on
different fields and for specific values same as elevate !!
