answer:It goes according to key words, yes. The search engine crawls the web, looking for the key words you input. The stronger the search engine, the deeper the search. Some serch engines use other search engines to cast a broader net. There’s one that uses (I think) 17 smaller search engines. The more specific your words in relation to each other, the closer your results you get back that match your search. Are you aware that quotation marks are the most specific way to get dead-on hits? Do you know how to do a Boolean search?
