[rules-users] Checking in one rule the "result" of another rule

[Swindells, Thomas]

Sounds like you want to use truthmaintenance and probably insertlogical.
There's a good tutorial/description on it here http://feeds.athico.com/~r/DroolsRSS/~3/BbuYJS41FDc/drools-inference-and-truth-maintenance.html

Basically, in your cases, you would insert a 'result' object with a given name for each of your base rules. Your user rules can then simply match the existence of whatever result objects that you wish in the standard manner.

> 4. I would like to build user rules out of base rules. For example: R = r0

> r0 = a given word the letter a appears more than twice
> r1 = in a given word the distance between 'a' and 'd' is 2
