The last step is to put a link on your home page to the search program. The link must point to /search/iaquery, but everything else is customizable.

Some example HTML:

<table border=1 width=100%>
<tr><td align=center>
<a href=/search/iaquery>
<FONT size=+2>Search this site</FONT>
</a>
</td>
</tr>
</table>

Which would look like:

Search this site
