Good and bad news.
I've worked out another way to do the same thing, but it's not exactly the same method as I was origionally going to use...
I'll keep you posted, but atm I'm still trying to figure it out for myself.
Basically, the search engine analyses the whole website (rather than just a single file), and then words used more frequently are generally considered to be less likely to be relevant. *However* if the site focuses on one word (eg: this site focuses on the word "english"), then this method would be broken. Therefor, it also looks at the html files, and considers text in bold tags to be sacred, and 'thou shall not give bad ratings to sacred words'. Then words such as "the" get smuggled into bold text, and make themselves appear sacred... Still working on a cure to this one, but it will be solved Maybe have some sort of holy water to dip words into. If it dies, it was not sacred...
