JESS: about partial match of a rule

[Guoli Li]

Hi, all, Now I'm using JESS. I have a question, and I'll show it with an example. Here are two rules: Rule 1: e1 ^ e2 => printout e1 and e2 happened Rule 2: e3 => printout e3 happend when e3 comes, I do the following: 1.(assert e3) 2. (run) rule 2 is fired, and e3 is only for rule 2, and I can retract it using (retract e3) after (run). While for e1 and e2 things are different. when e1 comes, no rules are fired, but their is a partial match of rule 1. I need to store e1 until e2 comes. My question is " how could I find when a fact triggers part of a rule?" and " can I retract a fact according to its content, e.g. the slot value?" Thanks a lot! sincerely yours, Li
