问如何使用过滤器"EQ“方法查找搜索字段的结果？

EN

onFilterProduct : function (oEvent) {
         // build filter array
        var aFilter = [], 
            //get the searchfield Id
            oInput = this.byId("productSearch"),

            oTable = this.getView().byId("idProductsTable"),
            oBinding = oTable.getBinding("items"),

            //get searchfield value
            sQuery = oInput.getValue(),

    if (sQuery) {

            //push matches into aFilter array                
            aFilter.push(new Filter("Product", FilterOperator.EQ, sQuery));

            oBinding.filter(aFilter);
        };
    };
