a lecture more precise into researching...

firstly, looking into facilities that will help to find quality materials on the internet.
the different types of search engines are, search engines, meta search engines, subject directories and the database a.k.a invisible web.

and i found out that the spiders/crawlers are the very links that link us within each website. the name is so weird that at first to me it sounds like some virus, haha... weird right...

there were also special search engines, that are categorized but they are unlike subject directories...

and i also find that the brackets, AND, OR, +, - are all easy to use and helps greatly to narrow down results of the search. '*' are also commonly used and all these all called BOOLEAN operators.

the various search engines also got many other features that i didn't bother look at as if they were white elephants...

and i also came across Google scholar beta, the search engine, it is mostly articles and more wordy, unlike the main Google that allows images, websites and audio etc...

i think during this period of taking this module, i really will learn to compare more features at every website and will look very into each detail :P
