我想查询已经加载到 Elasticsearch 5 中的嵌套数据,但每个查询都没有返回任何内容。数据是对象数据类型和json 的嵌套数组。
这是嵌套的数据类型,即 json 的 team_members 数组:
[{
"id": 6,
"name": "mike",
"priority": 1
}, {
"id": 7,
"name": "james",
"priority": 2
}]
这个对象数据类型,即availability_slot json:
{
"monday": {
"on": true,
"end_time": "15",
"start_time": "9",
"end_time_unit": "pm",
"start_time_unit": "am",
"events_starts_every": 10
}
}
这是我的弹性搜索映射:
{
"meetings_development_20170716013030509": {
"mappings": {
"meeting": {
"properties": {
"account": {"type": "integer"},
"availability_slot": {
"properties": {
"monday": {
"properties": {
"end_time": {"type": "text"},
"end_time_unit": {"type": "text"},
"events_starts_every": {
"type":"integer"
},
"on": {"type": "boolean"},
"start_time": {"type": "text"},
"start_time_unit": {
"type": "text"
}
}
}
}
},
"team_members": {
"type": "nested",
"properties": {
"id": {"type": "integer"},
"name": {"type": "text"},
"priority": {"type": "integer"}
}
}
}
}
}
}
}
我有两个查询由于不同的原因而失败:
查询 1 尽管弹性搜索中存在记录,但此查询返回的计数为零,我发现查询由于过滤器而失败:
curl -u elastic:changeme http://172.19.0.4:9200/meetings_development/_search?pretty -d '{"query":{"nested":{"path":"team_members","score_mode":"avg","query":{"bool":{"must":[{"match":{"team_members.name":"mike"}},{"match":{"team_members.priority":1}}],"filter":[{"match":{"account":1}}]}}}}}'
这将返回零结果:
{
"took" : 8,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : [ ]
}
}
没有过滤器的查询 1 上面没有过滤器的相同查询有效:
curl -u elastic:changeme http://172.19.0.4:9200/meetings_development/_search?pretty -d '{"query":{"nested":{"path":"team_members","score_mode":"avg","query":{"bool":{"must":[{"match":{"team_members.name":"mike"}},{"match":{"team_members.priority":1}}]}}}}}'
上面的查询返回 3 个命中:
{
"took" : 312,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 3,
"max_score" : 2.1451323,
"hits" : [{**results available here**} ]
}
}
对象数据类型的查询 2
curl -u elastic:changeme http://172.19.0.4:9200/meetings_development/_search?pretty -d '{"query":{"bool":{"must":{"match":{"availability_slot.start_time":1}},"filter":[{"match":{"account":1}}]}}}'
查询返回零命中,但数据在弹性搜索中:
{
"took" : 172,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : [ ]
}
}
如何让两个查询都按帐户进行过滤。谢谢
