I could solve it with cgi mapserver, template and form.
This example based on mapserver 4.x
Create a form in your html 
...
<form method="GET" name="mapserv" action="cgi-bin/mapserv">
<input type="hidden" name="map" value="_your map file_">
<input type="hidden" name="mapext" value="shape">
<input type="hidden" name="mode" value="itemquery">
<input type="hidden" name="qlayer" value="_layer name_">
<input type="hidden" name="qitem" value="_field name_">
Enter value:<input type="text" name="qstring">
<input type="submit" name="Find">
...

in your map file

you shoud ad
TEMPLATE
HEADER
FOOTER
to the queried layer.

I hope this help.

Bye
Zoltan
