<div><br></div><div><br></div><div>My use case is that I could have hundreds of rule and each rule could have its own set of strings.</div><div>A fact object is run through these rules to see which ones are fired.</div><div>


One of the condition to check is that the a list in the fact is not a subset of list in the rule. </div><div>That is fire the rule only if list in fact is not a subset of list in rule.</div><div> </div><div>Thanks</div><div>

OK, I admit I don&#39;t have the original thread anymore.<br><br>If I am not wrong (which is always a possibility) for Wolfgang&#39;s operator to work you&#39;d need to externalise the superset from the rule into WorkingMemory. You could have a rule with higher salience construct the superset WM fact.<br>



<br>If you don&#39;t mind re-posting or providing a link to the complete thread (on Nabble or somewhere) I&#39;ll happily try to help further.<br><br><div class="gmail_quote">On 12 October 2010 17:23,  <span dir="ltr">&lt;<a href="mailto:kumar.pandey@gmail.com" target="_blank">kumar.pandey@gmail.com</a>&gt;</span> wrote:<br>

Wolfgang gave a great solution.<br></div>
&lt;/quote&gt;<br>
Don&#39;t know if I&#39;m missing something obvious here.  I have a superset in the rule itself. Each rule has a superset list. In this case how would I use Wolfgang&#39;s solution. Its comparing through two arrays in runtime. I have not been able to construct an array construct with specific values in the rule itself.<br>
