 Hello, 
  is there any support for ad-hoc queries in Drools or are there plans to
introduce this feature ?
  Being part of the rule base queries are executed in the manner of prepared
statements. 
  To execute dynamic query patterns I currently create, add and remove a KB
package containing
  the query. It would be great to have a dedicated/optimized utility method
in Drools, that accepts
  a string pattern and returns QueryResults, like
WorkingMemory#getQueryResults. There were similar
  requests earlier [1], [2], but they were not responded with regard to
dynamic queries.
