Search for less than 3 characters.

Hi,

Is there any way to do a search and replace on less than 3 characters? A recent change of database left me with rogue characters in my text which I need to replace with the correct ones. Most of the rogue strings are 3 characters long, so are no problem, but somer are single digits which need deleting.

if I replace the 3 with 1 will it mess with the function of the module? or is the 3 char limit there for another reason?

function search_and_replace_settings_submit($form_id, $form_values) {
	if(strlen($form_values["search_term"]) < 3){
		form_set_error("search_term","You can't do a replace of a string less then 3 in length.");
		return false;
  	}

Cheers

Paul
