How does Google highlight their search terms?

for instance like this

Would it be possible to do this when a user clicks on a link to a site to make a point about something?

Slime made a script a while ago, if that's what you want.
Check http://www.ozoneasylum.com/Forum1/HTML/007226.html

It's built in with the Google core software. All v\commercial search engines have it. We had it at Verity too ... the word search index stores the document url and the byte offset for every occurrence of each word in that particular document. After that it's pretty east to cread the document as a bytestream and add a span class= ..... at the correct byte offset, and then (in the case of crude systems) highlight the search term precicely then add the /span tag ... or in the case of ore sophisticated systems (with stemming, soundex, typexetc, and/or theaurus, glossary etc.) to highlight the whole of the word which reflects the search term.


Bug-free software only exisits in two places
A programmer's mind and a salesman's lips

Here's how I do it in PHP:

if (isset($highlight)){

	$highlight = urldecode($highlight);

	$body = preg_replace("'$highlight'i","<span class=\"highlight\">\\0</span>",$body);

}

$highlight is grabbed from the URL, urldecoded (strips the "+"), then uses a css class called highlight to actually do the highlighting. An example can be seen at http://www.macombsheriff.com/articles/537/highlight/Pat+Richard

My mistake...

I neglected to mention that the above link, http://www.macombsheriff.com/articles/537/highlight/Pat+Richard

actually translates to http://www.macombsheriff.com/article.php?aid=537&highlight=Pat+Richard
hence, $highlight is being set to 'Pat+Richard' (please, no gay jokes there...). Then the code I posted takes $highlight and runs with it...

wow, pugz... in the past I had neglected to realize how your name could be extremely funny...
