Test DAY. The day before i browsed through the lecture notes quickly and thank god I could memorise most of them. And the questions were rather tricky. But good thing i did quite well in the test.
Today we used invisible web gateways to search for one resource. I used Complete Planet to search for the resource and it the site looked similar to that of a subject directory. It had categories to choose from. The page is simple and the search tab has special functions. After i keyed in my search requirement, i could choose if I wanted to search as a Boolean query, all of the words, any of the words or search it as a phrase. It helps me specify the type of search I want. It finds databases with highly relevant documents that cannot be crawled or indexed by surface web search engines.
Like the Meta Search Engines, there are not much resources listed. The lists, however, shows how relevant the page is.
The invisible web has limited results, and is neither as good or as bad as search engines, as there are pros and cons. The results have to backed by other resources.
I will still use the invisible web to search for resources, but there is probability that I have to use search engines for resources to back it up.
