Thank you mbethke. Yeah, this is exactly what I want to do. I'm following the code from the stackoverflow by stevenl. It works, but takes much longer time. One more thing worth to mention is my abstracts are full-text-indexed. And after searching in the abstract, I just want the associated primarykey and not the abstract. I have put the terms in an array and matching them with the abstract in mysql. Can you please help to modify the code. 

my $against = join ' ', map {qq/"$_"/} @foo;
while (my $PK = <FILE1>) {
    chomp $PK;

    my $sth = $dbh->prepare(qq{
       SELECT value
         FROM value_table
        WHERE primary_key = ?
          # no '+' so it can match against at least one of the words i
+n the list
          AND MATCH (column_text_indexed) AGAINST (? IN BOOLEAN MODE)
    });
    $sth->execute($PK, $against);

FILE1 has list of all primarykeys and FILE2 has the list of terms. Thank you for your help.
