Computer Science KS3 / KS4: Search Engines

The term 'Search Engine' is explained through everyday activities/events.

Computer Head is trying to find a single item in a pile of hay and is doing this by going through all the individual strands of hay.

His friend, Ada, suggests that a search engine would be the best way to search through lots of items to find the item for which he is looking.

She then teaches her friend about Boolean Operators and shows how they help to make searches effective.

This clip is from the series How to Think Like a Computer.
