    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{*}
