Boolean Operators

and (Boolean AND)

The 'and' operator returns Boolean true if both operands evaluate to true.  If either or both operands are not a Boolean type, then they are first cast to a Boolean using the rules of the $boolean function.

Example

library.books["Aho" in authors and price < 50].title

or (Boolean OR)

The 'or' operator returns Boolean true if either operand evaluates to true.  If either or both operands are not a Boolean type, then they are first cast to a Boolean using the rules of the $boolean function.

Example

library.books[price < 10 or section="diy"].title

Please note that Boolean 'NOT' is a function, not an operator.
