Question

I have multiple texts fields every field is paragraph of text and I want to search for a specifc pattern on those fields using regular expression for example:

my $text1 =~/(my pattern)/ig;
my $text2 =~/(my pattern)/ig;
...
my $textn=~/(my pattern)/ig;

I wonder if there are an effecint way to search multiple text with the same regular expression on perl or I should use the above format?
