Boolean Operators
and (Boolean AND)
The 'and' operator returns Boolean true if both operands evaluate to true. If either or both operands is 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 is 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.
