Re: [rules-users] Delimited Number groups filtering ?

Hello Again David / List, I should have probably mentioned that I'm working with Drools 3, I'm not sure how or "if" this can be implemented in Drools 3 syntax. I've tried to search Drools 3 documentation and googled for this. Currently I'm using contains with first finds the age groups then follows to find the matching Campaing but as I already know what campaign I'm checking and my intention is to check if this campaign can accept this age group I would like to reverese the search order... Ideas are very welcome. Happy new year everyone ! On Sun, Dec 21, 2008 at 10:20 PM, David Sinclair < dsinclair(a)chariotsolutions.com&gt; wrote: > u almost had it.
