in thread One line assigment statement with regex match

That way will nicely return a list of lines that have at least one of the terms in them. A variant will return a list of terms that are found in at least one line:
my @matches = grep { my $term = $_; grep{ $_=~/$term/}@lines } @terms;
It's unclear from the description which of these (or something else) the OP wants.
