Hi all- I currently use a javascript seacrh string on my website that searchs all folders (directories) and gives results on a html page. My problem is that some folders (or sub directories) are not being found when I type into the form search box. Does anyone know why this might be happening?

here is the script im using
<script language="JavaScript" type="text/javascript">function OnSearchSubmit(){var b_return=true;if (document.form_search.sw){for(var i=0;i<document.form_search.sw.value.length;i++){if (document.form_search.sw.value.charAt(i)!=" ") {lh="searchresult.html?sw="+encodeURIComponent(document.form_search.sw.value);b_return=false;break;}}}if (b_return) return;window.open(lh,"_self");}</script>
