Greetings
If you wanna search better on google try some of the things I talk about one this tut . Everything here is going to be about this site www.google.com. Well here goes nothing.
Some of googles myths:
1) Google's index is a snapshot of all that there is online.
No, not even google knows everything that is on the web. Every sec there is a new web site up, so it is impossible for google to keep up with the populion of the Internet.
2) Everything on the web is credible.
No it is not, There are things on the Internet that are just plan wrong.
3)Googles content filtering will protect you from offensive material.
HA, Even tho googles filtering is good, it's not perfect.
Generally speaking there is two types of search engines on the Internet. The first one is called the searchable subject index. Which is a kind of search engine that only searches titles and descriptions of sites and it doesn't search individual pages. Yahoo is a searchable subject index. Then there are full-text search engines which are computerized "spiders" which contain around millions and billions of pages. These pages can be searched by title or content, allowing for much more searches then searchable subject index. Google is a full-text search engine, that is why google is the best search engine in the world.
Whenever you search for more then one keyword at a time (e.x john brown AND bob heart) the search engine has a default method of how it handles the keyword. Will the search go of both keywords or for either keyword? The answer is called a Boolean default, the search engine can default to Boolean AND (it will search for both keywords) or Boolean, OR (It will search for either keyword). Of course even if a search engine defaults to searching for both keywords (e.x AND) you can give a command to intrust it to search for either keyword (e.x OR). A search engine has to know what to do if you don't give instructions.
