    • Expression: <value1> != <value2>
    • Operator: ATTR (string, number, time)

    ATTR

    return pi() != 3

    find().nodes() as n
    where n.level != 1
    limit 10
    return n{*}
    

    Analysis: both nodes that do not have @level property and nodes whose @level do not equal 1 will be filtered

    Property

    Example: Find information of 10 nodes that are not bank cards

    find().nodes({level != 1}) as n
    limit 10
    return n{*}

    Example: Find 10 bank cards whose level is not 1

    find().nodes({level != 1}) as n
    limit 10
    return n{*}
