bool过滤查询
bool查询可以实现组合过滤查询
格式：
{"bool" : {"must":[],"should":[],"must_not":[] } }
must：必须满足的条件 （相当于and）
should：可以满足也可以不满足的条件 （相当于or）
must_not：不需要满足的条件 （相当于not）
范围过滤
gt:>
lt:<
gte:>=
lte:<=

{
"query" : {
"bool" : {
"must": [
{"range" : {
"age" : { "gt" : 30 }
}},
{"match" : {
"last_name" : "smith"
}}
]
}
}
}
