Hey all! Hoping someone can help me solve a little problem.

I'm parsing a block of free text in a file, and I have a pre-loaded array of specific terms.

When I parse that block of text into a string, I'm looking to cross reference each word on that string with the terms I have on the array. If there's a match between the two, print it out.

        if($text =~ /upperboundary(.+)lowerboundary/s){

        if(grep {$_ eq $1} @terms){
            
        print OUT "$1\t";
        }
    }

This doesn't work, and I searched for a while on how to do it, to no avail. Can someone point me in a better direction? Thanks in advance!
