what is the difference between an ordinary search engine and a directory search engine?

Answer 1

Search Engines utilize indexing programs (often referred to as agents, spiders or robots) to constantly search the Web for new or updated pages going from URL to URL until, in theory, they visit every Web site which is referenced on the Internet. When visiting a Web site they record and index at least the full text of every page (home and sub-pages) within the site then continue on to visit all the external links. Following links, in theory, allows them to find sites regardless of whether registered . Submitting a URL however speeds up the process and if it is a new site there will not be any links.

Directories are quite different. They do not make use of indexing software so a directory can not list your URL unless you or someone else registers it with them. The registration needs much more information than just a URL. Directories are usually divided into many categories and sub-categories and you have to submit your URL under the most appropriate heading. In many cases the submission is reviewed by a real person before it is made available which can be very slow.

Answer 2

Nope...a regular search engine searches the whole internet for hits.

A directory search engine only searches within the available directories of that engine's creator.

For instance if you use directory search in Yahoo! It will only search for hits within the (pre-set up) directories/lists in Yahoo!

Answer 3

I think a directory search engine searches other search engines!!
Basically an ordinary seach engine is like google. But a director search engine will search google, yahoo, msm etc

Answer 4

reverse phone number search compiles hundreds of millions of phone book records to help locate the owner's name, location, time zone, email and other public information.

Use a reverse phone lookup to:
Get the identity of an unknown caller.
Identify an area code.
Recall the name of a person whose number you wrote down.
Identify an unfamiliar phone number that shows up on your bill.
