face="Times New Roman"><span style='font-size:12.0pt'>Collecting stuff from
several matches into a single Collector fact is best done<br>
by letting matches occur with rules at salience N. Then, put a single rule<br>
matching the Collector, without any constraints, at salience < N.<br>
This matches any Collector fact, and, in the consequence you should<br>
remove this fact, which has done its duty. To distinguish (as in your case)<br>
the successful case (one match) from others, you might just use an if<br>
statement in the consequence. (Well, yes, this isn't quite comme-il-faut,<br>
but it'll get the job done.) So, don't bother with updates on the Collector
fact.<br>
<br>
As for the frequently used && to connect the constraints, it is
preferred<br>
to use individual constraint groups, separated by a comma, for matches<br>
with different fact attributes. Constraint groups can be shared among<br>
rules (in the Rete node network) which is the essence of Rete being<br>
fast enough to cope with the many-many pattern matching effort.<br>
