Assuming that your criteria is not random and infinite you could write a query that accepts the criteria you are searching by. Take a look at section 6.6 of the user's guide. http://downloads.jboss.com/drools/docs/4.0.7.19894.GA/html/index.html I'm fairly new to Drools so I'm more book smart than I am practical right now but hopefully this will point you in the right direction.

Is there an efficient way to query for X random facts matching some constraint (e.g. ten random cheeses that cost less than 3 dollars)? I'd rather not generate the complete list if there's a more clever way. Unfortunately, the constraints are customer specific; otherwise, I'd just create sort of a central buffer list and dole out the random goodness to all takers. thanks, -Jess _____________ The information contained in this message is proprietary and/or confidential.
