You use Boolean operators to do searches. Without even know, you have used them!

They are AND, OR, and NOT

Use AND when you want to narrow down a search - A search for Germany AND Austria will only bring up results that mention both Germany AND Austria.

Use OR when you need to broaden your search - A search for Germany OR Austria will bring up any result that mentions Germany and every result that mentions Austria

Use NOT when you want to eliminate a keyword - A search for Higher Education NOT China will bring up results that talk about higher education in places other than China

Boolean operators can be combined. You could have a search that looks like this:
Higher education AND (math skills OR reading skills) NOT China
