Just search in a loop adding the highlighting as you go. Something like this: (untested)

my $index = '1.0';
while (my $result = $text->search(-nocase => "$word_search", $index, '
+end')){
    $text->tagAdd('color', "$result wordstart", "$result wordend")
    $index = "$result wordend";
}

If it is a large file, it may take a while to churn through; you may want to update your main window inside the loop so it doesn't "lock-up" while its working. This will add extra time to the process however.
