    var data = [
           { "x": 2, "y": 0 },
           { "x": 3, "y": 1 },
           { "x": 4, "y": 1 },
           { "x": 2, "y": 1 }
        ],
        res = JSON.search( data, '//*[ y > 0 ]' );

    console.log( res.sum('x') );
    // 9
    console.log( res.avg('x') );
    // 3
    console.log( res.min('x') );
    // 2
    console.log( res.max('x') );
    // 4
    res.multiply('x', 5);
    console.log( res );
    // [{ x=15, y=1}, { x=20, y=1}, { x=10, y=1}]

    res.each(function(row) {
        console.log( row );
    });
    // { x=15, y=1}
    // { x=20, y=1}
    // { x=10, y=1}
