      And

      Expression, Operand

      Combine and calculate the two expressions <exp1> and <exp2>, as in:

      <exp1> <exp2> Result
      0 0 0
      0 1 0
      1 0 0
      1 1 1

      Syntax:

      • Expression: <exp1> && <exp2>
      • Operand: expression (true, false)

      Common Usage

      Example: find 10 cards whose balances are over 500,000

      find().nodes({@card && balance > 500000}) as n
      limit 10
      return n{*}
      

      Analysis: this filter is a separated form from {@card.balance > 500000}, see Schema Filter &.

      Example: find 10 cards whose balances are greater than 500,000 and whose levels are less than 3.

      find().nodes({@card.balance > 500000 && level < 3}) as n
      limit 10
      return n{*}
