Most Search Engines store more than just the word and URL. As an example the Search Engine might store the number of times that a certain word appears on a page. It might assign a weight to each entry, with increasing values assigned to words as they appear near the top of the document, in sub-headings, in links, in the META tags and also in the title of the page.
