You don't gain any significant efficiency by grepping text files over 
storing the same information within a database.  As well, the search 
utility offered on the OCAL site was primarily text based.  Though they 
would sometimes display a PNG, more often than not it was just text.

Additionally, the server load to serve a 50k .gif is the same as to 
serve a 50k text file.  Graphics, unless being dynamically generated, 
only eat up bandwidth in the pipe, but don't really tax the server. 
It's the database queries and script processing that are the problem.

The ways to gain efficiencies there are to pre-make the output of 
certain popular database queries and update them periodically (such as a 
tag cloud that updates every 6 hours instead of updating live), or 
offloading some of the search effort to the client (via a Flash app that 
downloads an XML file and builds its own search index from it) or a 
third party (such as Google).
