Heroic Documentation

The structure of a filter is explained in detail in the Query Language documentation. This will only be a brief, syntactical overview.

Structure	Purpose
`["and", <filter>, ...]`	A boolean 'and' operation, evaluates to `true` if all of the nested `<filter>`'s are `true`, otherwise `true`.
`["or", <filter>, ...]`	A boolean 'or' operation, evaluates to `true` if any of the nested `<filter>`'s are `true`, otherwise `false`.
`["not", <filter>]`	A boolean 'not' operation, evaluates to `true` if the nested `<filter>` is `false`.
