Accumulate functions are very well documented in the Expert manual. Look for a section titled "Accumulate Functions".<br><br>You could also use accumulate with all the steps in inline code, which is documented in the preceding section.<br>

Thanks for outlining the approach, Edson.<br>
<br>
Unfortunately, I'm a newbie using drools, so I just need some clarification<br>
on what you mean by 'matchAll is your own accumulate function with the<br>
semantics you described.' ? Do you mean that I have to create a 'custom'<br>
accumulate function ?<br>
<br>
Edson, if that's the case, then I'll try to search for example of creating a<br>
custom function. When I last searched, I did find an example on the<br>
Internet, however, I don't think I found details of how to make the function<br>
available to the rules engine (is it as simple as including the jar in the<br>
classpath or do I need to take addtional steps to use Matchall in drl ?)<br>
<br>
Can you please elaborate for the benefit of a noobie ?<br>
<br>
Thanks<br>
Gurvinder<br>
