The term 'search engine' is explained through everyday activities and 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 he is looking for. She then teaches her friend about Boolean operators and shows how they help to make searches effective. Teacher notes: This video could be used to discuss AND, OR and NOT in relation to logic gates and circuits. You could also use it to discuss truth tables, conditional operators and George Boole, and his connection with Boolean operators.
