[rules-users] case in-sensitive string comparison?

[Michael Anstis]

You could look at using your own custom operator.

Wolfgang Laun linked to an article of his recently explaining the approach.

I'm not sure if custom operators however allow for indexing in the RETE
network and therefore whether they're any faster than eval.

Wolfgang, Edson, can you advise in your experience?

Thanks,

Mike
