sql - Building a search script in PHP -

-

i'm trying build search script in php-sql facebook or stackoverflow uses. example, user may put in multiple entries; separated semi-colon , autocomplete on each term. also: values stored in sql; type of data should use or how should insert terms in sql table??

<script type="text/javascript">  $().ready(function() {  $("#job_type").autocomplete("get_job_list.php",  { width: 224, matchcontains: true, selectfirst: false }); });  </script>

php code::

<?php  require_once "connection.php"; $q = strtolower($_get["q"]); if (!$q) return; $sql = "select distinct itemid itemid eportal itemid '%$q%'"; $rsd = mysql_query($sql); while($rs = mysql_fetch_array($rsd)) {     $cname = $rs['itemid']; echo "$cname\n";  }  ?>

add chosen tags separated table structure query_id tag_id (you need table tags structure tag_id tag_name. way query way easier , faster. moreover, able popular tags easily. sql meant storing data that. putting comma separated values against basics of sql.
