Students are advised to use the MLA format, while teachers are encouraged to use the APA format. There are several things to know about searching the Internet. Most search engines and directories recognize two or more words enclosed in quotation marks as phrases or keywords that are linked together. Before we get to the active links in the table below here are brief definitions for Search Engines and Directories. A search engine uses the exact words used on Web pages and other resources on the Internet, this means the search results can have a large number of hits.
Search engines are very specific if the spelling is correct.
But they can in fact be too broad which is why it is necessary to narrow the search. A search engine is a machine-made index. A directory uses logical subject categories developed by the creators of the directory. Directories are better when searching for general information but they do not search the entire Internet. A directory is a man-made index.
