explain查看怎么计算得分的，format将json格式结果转为yaml展示

POST tlsmz/_search?format=yaml
{"explain": true, "query": {"bool": {"must": [{"term": {"fz.keyword": {"value": "南昌西"}}},{"bool": {"should": [{"match": {"dz": "长沙"}}]}}]}}
}

通过/index/_explain/id 可以看到我们的文档是否被匹配，为什么匹配/不匹配。详细的原因

GET tlsmz/_explain/A53AC90D8F3941B8E055000000000001
{"query": {"bool": {"must": [{"term": {"fz.keyword": {"value": "南昌西"}}},{"bool": {"should": [{"match": {"dz": "长沙"}}]}}]}}
}

{"_index" : "tlsmz","_type" : "_doc","_id" : "A53AC90D8F3941B8E055000000000001","matched" : false,"explanation" : {"value" : 0.0,"description" : "Failure to meet condition(s) of required/prohibited clause(s)","details" : [{"value" : 0.0,"description" : "no match on required clause (fz.keyword:南昌西)","details" : [{"value" : 0.0,"description" : "no matching term","details" : [ ]}]},{"value" : 0.0,"description" : "no match on required clause (dz:长沙)","details" : [{"value" : 0.0,"description" : "no matching term","details" : [ ]}]}]}
