Invisible web(DATABASE)

OH HI GUYS! We were thought how to use the functionality of invisible web and we were asked to compare is it more effective to search the invisible web than using search engine, meta-search engine or subject directories.EBSCOhost search facilities has many functions that allows the user to do a very detailed research (e.g the search box contains various boolean functions as well as 3 kinds of searches - basic, advanced and even visual. It even has a history option for us to dig through our previous searches thus saving us the trouble to search for the information again. I find that EBSCOhost search facilities is very similar to the Google search engine in terms of the availability of information, various search functions to provide more specific results as well as options for images.
