You can connect directly to previously visited sites using this list. Cache maintenance occurs at exiting. Cache Search Engines - help you find sites related to a specific topic. Some will rank the relevancy of the links depending on how many times the words appeared in the pages. Each Search engine builds a database of web pages by using a program called a spider which crawls down the internet pipeline and adds new web sites to the database.
Some engines store all of the information on each web page it finds.
The larger the database the greater number of hits or links returned. Altavista is this type of engine, but because it brings back too many irrelevant hits, it is best used for very specific information. Each search engine has its own searching rules. Using - in front of word excludes it. Note Netscape needs pictures as GIF or jpg file extensions.
