orderByAscending

public LCSearchSortBuilder orderByAscending(String key,
                                            String mode,
                                            String missing)

按照key升序排序

Parameters:

key - 排序的key

mode - 数组或者多值字段的排序模式，min表示取最小值，max取最大值，sum取综合，avg取平均值，默认值是avg。

missing - 当搜索匹配的文档没有排序的key的时候，设置本选项决定文档放在开头还是末尾，取值是"last"或者"first"， 默认是"last"表示在末尾。

Returns:

Returns current object, so you can chain this call.

按照地理位置信息远近排序,key对应的字段类型必须是GeoPoint。

Parameters:

key - 排序的字段key

point - GeoPoint经纬度对象

order - 排序顺序，升序"asc"，降序"desc"，默认升序，也就是从近到远。
