Hi Monks,
I want to check if a word from a very large list of words exists in the first column of a (very large again) tab delimited text file, and if so to use some of the other columns from the latter to perform some actions on the former.
I got it to work, and then optimized my code the best I could to make it quicker. Still, I'm pretty sure it could be done in a more efficient way that I can't think of, as there is a bottleneck when looping through the tab delimited text file.

Here is the function I use to go through it and check if the word exists in it : 
sub lexique 
{
foreach (@lexiques)
{
        my @lexiks = split/\t/, $_;
        chomp @lexiks;
        my $motlexique = $lexiks[0];
        my $genre = $lexiks[4];
        my $nombre = $lexiks[5];
        if ($motlexique eq $thewordimsearching)
        {
            #Do some things here
            last;
        }
    }
}

Could you guide me a bit here ? Please keep in mind that I'm self-taught and not-so experienced with Perl.
