# bool过滤查询，可以做组合过滤查询
# SELECT * FROM books WHERE (price = 35.99 OR price = 99.99) AND (publish_date != "2016-02-06")
# 类似的，Elasticsearch也有 and, or, not这样的组合条件的查询方式
# 格式如下：
#  {
#    "bool" : {
#    "must" :     [],
#    "should" :   [],
#    "must_not" : [],
#    }
#  }
#
# must: 条件必须满足，相当于 and
# should: 条件可以满足也可以不满足，相当于 or
# must_not: 条件不需要满足，相当于 not

# 另外一种 and， or， not查询
