Presumably a search engine is simply a database of keyword -> result, 
possibly with some scoring factor.

Calculating scoring factor is going to be fun.

Then of course result pages might have scoring factors too. What about a 
search with multiple keywords. Some result pages might match more than 
one keyword, so you might add their score for each keyword together to 
get the ranking in that enquiry for that page.

But then pages with lots and lots of different keywords might be low 
scoring, because searchers are looking for content, not pages of keywords.

Finally, What special, unique feature is your search engine going to have 
that makes it better than all the existing ones?
