Interesting Smart Surfing

In Te Ngahere we have been learning about Smart Surfing. For Smart Surfing we have to find keywords in a question and then use those keywords to type into Google because if we type the whole question it would find all of the pages that has how on them. For example if I ask Google what do spiders eat it would find all of the documents that have, what and do, but if you just right that keywords like spiders diet it would give you a perfect answer about spiders eat. Have you learnt about this before?
