X-Cart forums - set minimum number of characters in search string. HOW PLS?

I was able to find something to prevent the blank searches and minimum characters. Set the var minLength to desired character length.

here is the capture section in search.tpl

Code:

{capture name=search}

<TABLE border="0" cellpadding="0" cellspacing="0">  

<FORM method="POST" action="search.php" name="productsearchform"  OnSubmit="return submitSearchFrm();">

<INPUT type="hidden" name="simple_search" value="Y">

<INPUT type="hidden" name="mode" value="search">

<INPUT type="hidden" name="posted_data[substring]" value="" id="search_substring">

<INPUT type="hidden" name="posted_data[by_title]" value="Y">

<INPUT type="hidden" name="posted_data[by_shortdescr]" value="Y">

<INPUT type="hidden" name="posted_data[by_fulldescr]" value="Y">

<TR> 

 <TD align="right" valign="middle">

{literal}

<SCRIPT language="JavaScript">

function submitSearchFrm() {

          var minLength = 3;

          var frm = document.productsearchform;

        if (frm.search_for.value == "" || frm.search_for.value.length < minLength) {

                alert ("Please enter a minimum of 3 characters");

                return false;

        }

        var search_substring = document.getElementById("search_substring");

        search_substring.value = frm.search_for.value;

        return true;

}

</SCRIPT>
