Code please? ;-)
I suspect that currently you're using something like
s/$search/<b>$search<\/b>/gi;
and you can replace that with
s/($search)/<b>$1<\/b>gi;
Actually, the above is quite unsafe WRT tainting, because you have no
control to what people enter. They can enter any regex, if it's not a
valid regex, this code will die. quotemeta() can prevent that, allowing
only literal searches:
s/(\Q$search\E)/<b>$1<\/b>/gi;
'\Q' is the inside-a-double-quotish-string drop-in replacement for the
quotemeta() function.
