Find a word in a part of sentence for condition

[Daniel_Pelissier]

What is the similar way to write and find a word in a sentence, like « oil nuts»…want to tell ok if find oil in the sentence…as we could do with «oil.*»

Thank you

Use the contains text block

[Daniel_Pelissier]

I try this simple exemple but doesn t work

[TIMAI2]

Like this:
(assumes the content of Label2 = oil)
(the contains block will return true or false)
