Is there some operator that finds a substring in a string on cms modx?

Question

MODX

Seems like an elementary thing. Googled but didn't find anything. Help.

Answer 1

pdoTools fenom has this feature.
In the basic version of modx before 2.2, there was also such an opportunity, but it seems to have been removed.
All that's left

Answer 2

strange requirement.
if logic is needed, then it is done in snippets on standard php + modx API,
why is there an operator on the backend that finds a substring, I don’t know. PHP has a function...
