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.

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.

Subject: [rules-users] returning random limited query results

 

I'm trying to implement some suggestion functionality.  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,
