There are two types of databases for searching on the web. There are site-specific search engines that locate material contained within a specific website, and there are web search engines that locate information widely from across the web. Both of these types of search engines have the same sorts of functions. What differs between them is how the database being searched was created, how searches within that database are best conducted, and what kind of information you’ll be retrieving from the database.
The first thing you should do when you go to an unfamiliar search site (or even one you’ve been using, but with some degree of frustration) is to find the search “help” file. Spending a few minutes with the help file will get you ready to do a thorough and effective search.
