      Expression, Operand

      <> judges if a given <value> is in a closed interval between <lower> and <upper>, with <value> greater than or equal to <lower> but less than or equal to <upper>. It only makes sense when <lower> is less than or equal to <upper>.

      Syntax:

      • Expression: <value> <=> [<lower>, <upper>]
      • Operand: ATTR (string, number, time)

      Constant

      Example: judge if "abc" is in the closed interval ["asd", "1af"]

      return "abc" <=> ["asd", "1af"]
      

      Function

      Example: judge if PI is in the closed interval [3.14, 3.15]

      uncollect [3.14, 3.15] as a
      with collect(a) as b
      return pi() <=> [b[0], b[1]]
      

      Alias

      Example: find 10 nodes whose levels are in the closed interval [1, 3]

      find().nodes() as n
      where n.level <=> [1, 3]
      limit 10
      return n{*}
      

      Property

      Example: find 10 nodes whose levels are in the closed interval [1, 3]

      find().nodes({level <=> [1, 3]}) as n
