How I can make a filter in my query multiple

var Quoteid = "121D466B-9765-E611-80D3-00155D00D107";

XrmServiceToolkit.Rest.RetrieveMultiple(
            "QuoteDetailSet",
            "$select=ProductId, Quantity, PricePerUnit, ManualDiscountAmount, ExtendedAmount, QuoteId & $filter=QuoteId eq "+Quoteid,
            function (results) {
                $scope.products = results;
            },
            function (error) {
                $scope.products = error;
            },
            function onComplete() {

            },
            false
        );
