I have a .txt logfile and want to search in the file for a piece of text.  
If the text is in the file i like a true output and not a false output

i found and tried this flow but always displays false... does anyone know what's wrong?

Please take note of the pinned message and put your code between triple back-ticks. As it is, it is unusable. Thanks.

As I think you are using a function node to do the search (?), it may be easier just to show that code separately.

Can you post the logfile somewhere (or post some example lines) and the string you are trying to find ?

To check if element exists in array use  
`yourArray.indexOf(element) != -1`

What you are doing currently is the check if the entry is in array and is not first element of that array
