Hi everyone.

I have a fairly simple question, but the answer is likely to be very
complex. I would like to create a wiki that will allow full-text
searches. However, as you know, full-text searches in a large database
is very CPU intensive. I need to look into what options are available
in the way of breaking everything down into keywords, and how I'd do
it efficiently. I know that there is no definitive answer to my query,
but I have no idea where to start looking. I would like to make my
wiki very much like a small-scale search engine. Much like Google, but
far, far smaller by comparison.

Google doesn't just do a full-text search on the several billion pages
it has stored every time you make a query. They evidently have some
algorithm running behind it all which breaks everything down very
efficiently indeed.

I would very much appreciate it if anyone could point me in the right
direction, with any suggestions, whether thy be logic, documents I
should read, or terms I can Google.

Thanks in advance.

Daz.
