Thanks Olly :-)

Your advice supported a successful implementation.  After upgrading to
Xapian 1.2.5, a new template was created, based on the standard "query"
template:

root at CW8vDS:/var/lib/omega/templates# diff -u query docoll 
--- query	2011-04-04 20:48:48.000000000 +0530
+++ query_dev	2011-04-24 13:27:50.435175754 +0530

 <center>
 <INPUT NAME=P VALUE="$html{$query}" SIZE=65>
 <INPUT TYPE=SUBMIT VALUE="Search">

-$if{,$include{inc/anyalldropbox},$include{inc/anyallradio}}
+<br><br>

 $if{$opt{topterms},
  <div title="Suggested terms to add to your query"
  style="text-align:left;background:#cfc;border:1px solid
green;padding:2px;font:11px verdana$. arial$. helvetica$. sans-serif;">

Here's the helper fragment, filenamedropbox

<SELECT NAME=B>
<OPTION VALUE="" SELECTED>Any
<OPTION VALUE=Edoc>.doc
<OPTION VALUE=Edocx>.docx
<OPTION VALUE=Eodp>.odp
<OPTION VALUE=Eods>.ods
<OPTION VALUE=Eodt>.odt
<OPTION VALUE=Epdf>.pdf
<OPTION VALUE=Epps>.pps
<OPTION VALUE=Eppsx>.ppsx
<OPTION VALUE=Eppt>.ppt
<OPTION VALUE=Ertf>.rtf
<OPTION VALUE=Etxt>.txt
<OPTION VALUE=Exls>.xls
<OPTION VALUE=Exlsx>.xlsx
</SELECT>

An issue with this implementation is that it only allows specifying a single
file type; it would be nice to choose several.  Adding MULTIPLE to the
SELECT tag uses too much vertical space and CHECKBOXes only give on/off
values.  Hmm ... 

Regards finding Omega templates on the web, your observations are correct
and searching for "OmegaScript" with "template" turned up very few actual
templates.
