You can attach the search functionality of your web site right into MSIE 7.0. If you're using IE7, check out the search widget and see for yourself.

What you need:
- An XML file (or script that generates XML) in the Open Search Description schema.
- Add a <link /> tag in the <head> section that points that XML file or script
Here is the link tag I added to the hometemplate.blogtemplate dasBlog file:
<link rel="search" type="application/opensearchdescription+xml" href="/blog/opensearch.xml" title="In Chris Velazquez's words" />
I put this right before the line that has <%radio.macros.headLinks ()%>. I'm not a dasBlog guru, or I would figure out how to get this in as a headLink. Suggestions are welcome!
Now I need the file (opensearch.xml) that it points to:
<?xml version="1.0"?>
<OpenSearchDescription
xmlns="http://a9.com/-/spec/opensearch/1.1/">
<ShortName>In Chris Velazquez's words</ShortName>
<Description>In Chris Velazquez's words</Description>
<Url type="text/html" method="get" template="http://www.chrisvelazquez.com/blog/SearchView.aspx?q={searchTerms}"/>
</OpenSearchDescription>
The template attribute has {searchTerms}, which is where the parameter would normally be entered.
Here are some of the custom search providers I use in MSIE 7
