The index links below work best if you allow your web browser to load the entire page first. Top Ten Things to Remember Search engines are not perfect. Search engine software is only as good as the programmers that write the code. Search engines are created by various human beings, thus they each work a bit different from one another.
Similar commands can have different search effects on different search engines.
Collectively, the major search engines have indexed approximately sixty percent of the Internet. Each search engine has indexed a slightly different portion of the Internet than other search engines, with some overlap occurring between search engines. After using a search engine, if you don't find what you are looking for, that doesn't necessarily mean that it doesn't exist online. It may only mean that particular resource hasn't yet been indexed. Revisit search engines often because their indexes are updated at regular intervals.
