This question is being asked by every absolut begginer on the Internet. Many users at novice level on the Internet will use the biggest search engines
for this. That is wrong. Main general search engines should be used in case that you need some general, lightly informations about certain theme.
If you are looking for
informations like this, it is recommended to use categories at main general search engines. But if you are looking for some specialty, detailed informations, searching
like this will become your nightmare.
In this case you should find some specialty search engines for certain theme. Specialty search engines are same like general, but
their database contains only URLs which content is certain theme: sport, music, marketing... You can use general search engines to find specialty search engines. There
is no universal rule, but the best way is to choose certain theme from categories or subcategories and find subcategory in it, called "Search Engines" or "Directories".
The second way to solve this problem is to visit www.search.com. This location is recommended if you are looking for speciality search engines.
It contains only URLs of speciality search engines and directories.
