We are stuck with the search engine that comes with vbulletin. If you don't like our search engine, why not use another one instead? As one example, this will search our site for "sed". reborg and Neo have spent a lot of time making our site easy for the crawlers used by the major search engines. And they are working closely with Yahoo and Google. Personally, I fall back to Google when I can't find something here.

Alternatively, you can suggest changes to vbulletin to the vbulletin developers on the vbulletin site. But it's not likely that will ever match Google's software and even if they did we would not have the computing resources required to run it.
