Re: [rules-users] Matching strings in two arrays

Hi, In your fisrt post you mentionned that the test is ti check that your array contains ALL 3 string. Thus this is not a OR, but a AND Using Thomas trick which consist in given elements as facts, you could use a rule that looks like this : rule XYZ $p : MyContext ClassName(parent == $p, name == "TestString1") ClassName(parent == $p, name == "TestString2") ClassName(parent == $p, name == "TestString3") then ... and then exploiting also condition factorisation in RETE network. This will be even more efficient if your MyContext is the only one in WM, and then you can remove your condition on parent in ClassName pattern match. I guess that in 5000 rules, there are a lot of similar condition which could take avantage of such decomposition.
