How to test for existence of string in a field using Expression Language

[Peeves02]

Good day everyone.

I was trying to add a business rule with the following logic:

If the request title contains the words critical or down, then raise an incident.

I tried using the following code but it doesn't work:

${contain(entity.DisplayLabel, 'critical') || contain(entity.DisplayLabel, 'down')} Set ServiceImpact to true

I tried this too but doesn't work:

$match_pattern(entity.DisplayLabel, '*critical*') Set ServiceImpact to true

Can someone please show me how it's done.

When I try just a simple $entity.DisplayLabel == 'critical' Set erviceImpact to true, it works. 

But I need to test for the existence of string.

Thanks and regards.

Hello,

The match_pattern rule should work, I tested your rule.

The "contains" will not work, it applies to collections.

Thanks Brindusa.  I went back to my code and try changing the synrax and the below works.  Thanks for your tip.
