Example usage

For the examples we will assume the following payload:

{
  "people": [
    {
      "general": {"id": 100, "age": 20, "other": "foo", "name": "Bob"},
      "history": {"first_login": "2014-01-01", "last_login": "2014-12-02"}
    },
    {
      "general": {"id": 101, "age": 30, "other": "bar", "name": "Bill"},
      "history": {"first_login": "2014-05-01", "last_login": "2014-05-02"}
    }
  ]
}

Example of simple expression:

"people[?general.id==`100`]"

Example of a NOT expression:

{'NOT': "people[?general.id==`100`]"}

Example of an AND expression:

{
    'AND': [
        "people[?general.id==`100`]",
        "people[?history.first_login==`2014-05-01`]",
    ]
}

Example of a composite expression (nested:

{
    'AND': [
        "people[?history.last_login==`2014-12-02`]",
        {'NOT': "people[?general.age==`20`]"},
    ]
}
