So.... A complete index of my site is too large...
So I could chunk the index up... For example, one index for words beginning with each letter of the alphabet. I could host the index for words beginning with 'a' at mysite.com/search/a
But I could do yet smaller indexes! I could make one index for each word. Ie. use the URL mysite.com/search/abacus
We could call these mini-indexes search result pages...
