使用一个跨度查询作为查询背景，另一个查询作为真正的查询，从而圈定查询背景

Span Containing Query

组合多个跨度查询，并能指定那些查询结果（little）必须在什么情景（big）下出现

参数：

• little：要查询的语句，支持其他跨度查询
• big: 查询语句所处的大背景，little查询的结果必须是big的结果之一

说明：属于从大往小的查询，使用big子句区间的开始位置查询

Span Whithin Query

使用方式与Span Containing Query 一样

区别：属于从小往大查询，使用little子句区间的开始位置查询

#  whithin 包含
# -----------------------------------------------
#  Rose gives a lingering fragrance in the hand 
#   1    2    3     4         5     6    7   8
# -----------------------------------------------
#  big startPosition=4 endPosition=8  [4,8]
#  little startPosition=5 endPosition=6 [5,6]
#  从 position=5 开始检索
