Chris Brooks mentioned today that I need to add Search to my blog.  Until I get my Google Juice up, he's totally right.  So, I added the new dasBlog 1.5 standard search (notice the search box to the left) and then took the Google Highlighting javascript code and modified it thusly:

function googleSearchHighlight() {
if (!document.createElement) return;
ref = document.referrer;
//START Added by Scott Hanselman
if (ref.indexOf('?') == -1 || ref.indexOf('hanselman.com') != -1) //catch when I'm my OWN referrer!
{
ref = document.location.href;
if (ref.indexOf('?') == -1) return;
}
//END Added by Scott Hanselman
qs = ref.substr(ref.indexOf('?')+1);
qsa = qs.split('&');
for (i=0;iqsip = qsa[i].split('=');
if (qsip.length == 1) continue;
if (qsip[0] == 'q' || qsip[0] == 'p') { // q= for Google, p= for Yahoo
words = unescape(qsip[1].replace(/\+/g,' ')).split(/\s+/);
for (w=0;whighlightWord(document.getElementsByTagName("body")[0],words[w]);
}
}
}

So this will highlight words on my site when you search from Google, Yahoo, or use the internal search.  
Give it a try!  Here's a link that searches for XmlSerializer.
