No wonder sometimes I don't find what I am searching for, until I start doubting my keywords!
Sasa I know the reason. There are times I have searched for items until I got frustrated.

I'd like to know, if someone cares to explain in summary, how these other search engines work. How do they penetrate the deep Internet?

@Wash, in my recent experiments with DSpace, I learnt that a lot of universities and research organizations publish their works via this piece of software and its pretty easy to deny Google bots access to this honey pot of information.

To put it another way, suppose KIPPRA, KARI, KEMRI, all universities and other bodies which generate 'new' knowledge chose to NOT release their works to the public internet, Google would not find it and thus, you would not find it. I assume then that this is what is called deep internet, no?
