I was taking quiz about search engine for fun then i realize that it's good to summarize it and post it, to give you more information just in case you miss one :) -- But before i start i just want to tackle why search engine important? Because it makes more easier for us to find information rather than linking it to yourself, information are very well sorted and ready for you without any hassle; just like index card(Every thing is sorted) and most of all with search engine you're search is narrowed down to the exact information you needed.
-- Below are the facts about search engine:
- Google search engine has the largest index listing on the web and index's at least 8 billion pages.
- One query from google is limited to 32 search terms.
- Site owners site will be found by search engine using two different ways: search engine spiders index the information, or site owners submit it manually.
- A wildcard (A wildcard is a special character, usually an asterisk, that can be used as a substitute for another word or phrase) can be used to improved your search engine searches aswell as using special syntax and boolean search helper.
A metasearch engine is A search tool that doesn't have its own listings, but searches the indexes of other search engines.Do you know...
a search engine spider downloading a page and storing it on the search engine's own server, where a second program, known as an indexer, extracts various information about the page, such as the words it contains and where these are located, as well as any weight for specific words and all links the page contains, which are then placed into a scheduler for crawling at a later date.
