That's most puzzling because when I look at the searchlet, it seems pretty straightforward, albeit more complex HTML than it needs to be. Let's step through it and see what we can figure out, okay?

Rather than start out with their full, complex, HTML, here's the core search box for just your own Blog:

<form method="get"
 action="http://technorati.com/cosmos/search.html">
<input type="hidden" name="sub" value="searchlet" />
<input type="text" name="url" maxlength="255" value="" />
<input type="hidden" name="from"
 value="http://www.intuitive.com/blog/" />
<input type="submit" value="Search" class="search" />
</form>

This is a very basic search form and lets you search for recent weblog entries on my other weblog, The Intuitive Life Business Blog. Try it: search for 'HP' or 'trade', as examples:

That works, right. Now, the question is, how do we tweak this code for your blog, Neville. This is where a little experimentation comes in handy! Replacing the value attribute of the from tag with your base URL doesn't work:

<input type="hidden" name="from"
 value="http://www.nevon.net/" />

In fact, when I searched for 'skype' it showed me a whopping 16,000 matches. You're prolific, but not that prolific, mate!

My second attempt was to use the URL http://www.nevon.net/nevon/" and lo and behold, it worked just fine. A search for 'skype' produced six matches, not sixteen thousand. So, here's the minimalist Technorati searchlet for your site, Neville:

<form method="get"
 action="http://technorati.com/cosmos/search.html">
<input type="hidden" name="sub" value="searchlet" />
<input type="text" name="url" maxlength="255" value="" />
<input type="hidden" name="from"
 value="http://www.nevon.net/nevon/" />
<input type="submit" value="Search" class="search" />
</form>

Try it here:

Now that we have the basics out of the way, here's the full blown Technorati search box -- with a wee additional CSS tweak or two -- for my own Intuitive Life Business Blog site: simply change the code in red and you should be just fine...

<style type="text/css">
.legend { font-size:80% }
.legend a,.legend a:link,
.legend a:vlink { color: #009; text-decoration: none; }
.legend a:hover { text-decoration: underline; }
</style>
<form method="get" action="http://technorati.com/cosmos/search.html"
 style="width:12em;text-align:left">
<fieldset style="padding:4px">
 <legend><span class="legend"><a
  href="http://technorati.com/">Technorati</a>
  search</span>
 </legend>
<input type="hidden" name="sub" value="searchlet" />
<input style="width:12em" type="text" name="url"
 maxlength="255" value="" /><br />
<input type="radio" checked="checked" name="from" id="ts_yb"
value="http://www.intuitive.com/blog" />The Intuitive Life<br />
<input type="radio" name="from" id="ts_www" value="" />All
weblogs</label><br />
<input type="submit" value="Search" class="search" />
</fieldset>
</form>

And displayed:

I hope that helps you out!
