Standard JSONata Boolean operators available in expressions throughout the Fuuz platform.

## `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`

> **Note:** Boolean NOT is a function (`$not()` — see [Boolean Functions](https://www.fuuz.com/help/boolean-functions)), not an operator.
