Thats all very interesting to tech savy minded individuals, however your main target audience is the general public who would not understand a word of that.

Google is the most popular search engine because the general public liked it and now everyone knows about it. Google is simple.

Simplicity is your key here. If you are to be sucessful you need to make your advanced options very simple to understand to the general public.

Simple quick explinations as to why they should use your search engine. You should write this while imagining someone very stupid and lazy as the person who will be reading it - someone who doesn't even read properly - just scans the text quickly looking for simple one line explinationions like a mad man.
This is what the vast majority of the net do when looking at websites. Confuse them with too many tech savy terms and they will click away to the next site.

Once you have built up your public users... the webmasters and advertisers will follow.
