Capital Letters – The Key To Boolean Success

I’m about to share one of the most common things that people don’t realise about Boolean searching.

Boolean Ven

Boolean logic covers the operators AND, OR and NOT. The name comes from English born mathematician George Boole – his work with algebraic logic is the basis of the modern computer.

When were you last nagged about using capital letters? When you were in Primary school? Not if you’ve recently been in a training session with me.

When using these Boolean operators with a Search Engine, like Google or Bing, it is important to capitalise them.

A Search Engine automatically strips small words like and, or, if, but etc. out of your query. It only searches for what it considers to be a real keyword. By capitalising AND, OR and NOT we make sure the Search Engine takes notice of them as a Boolean operator.

Most job boards do not enforce this rule, so if you don’t usually capitalise your ANDs, ORs and NOTs you have probably still been having success when you search there. I tend to capitalise these operators as a rule – then my string will work everywhere.

The only problem is, I now automatically capitalise OR all the time – not just when I’m searching – Doh!
