what are the boolean operators? tomrecht 3/21/12 5:27 PM
An article named "Boolean Operators" ( says, "You can use boolean operators such as 'OR' when searching in Gmail".  An appended comment says that NOT is represented by '-'.

Is that it?  Or are there other booleans available?

In an article, "Using advanced search" (, there's a table that includes OR, parenthesis (which act sort of like AND), and '-' (NOT), but it also says "Some of the most useful operators are listed".

Are there other booleans?  As for searching, what are the "less useful" operators?

The only boolean operators that make sense for string searching are AND, OR, and NOT (-).  What else did you have in mind?

You've found the Google help article.  Here's another site that give more useful information...

I had in mind whatever was meant when they said, "Some of the most useful operators are listed", but didn't provide a list.  I was also interested in whatever they consider less useful than "the most useful" ones that were on the list that I couldn't find.

Sometimes I just like to look through my toolbox and see what I have. It helps me choose what I need when I'm trying to solve a problem.

However, all that aside, THANK YOU for the link! I don't know whether it was my clumsiness in trying to find it or Google's expertise in stowing it so I couldn't, but I didn't.
