让我们开始吧:
- 您似乎错误地映射了嵌套路径,它
oracle_props
是db
示例文档中的子项,而不是映射中的子项,在映射中它直接显示为根的子项。 - 您将映射
oracle_props.@value
为long
,但Y
在CREATE_PERMISSION
嵌套文档中为其分配了文本 - 您查询
range lt 4000
,但 不包括 4000,lte
适合您
我没有得到您要求的缺失值,因此我跳过了它。
为了使您走上正确的道路,我必须对它进行一些简化(因为我无法完全理解问题中的所有问题,对不起)
我也不打算进行渗透,而是将所有内容重命名为twitter / tweet,因为这对于我从示例中复制而言更容易。
1)创建空索引“ twitter”
curl -XDELETE 'http://localhost:9200/twitter/'curl -XPUT 'http://localhost:9200/twitter/'
2)为实际的“ tweet”创建geo_point映射
curl -XPUT 'http://localhost:9200/twitter/tweet/_mapping' -d '{ "tweet": { "properties": { "db": { "type": "object", "properties": { "@type": { "type": "string" }, "oracle_props": { "type": "nested", "properties": { "@name": { "type": "string" }, "@value": { "type": "string" } } } } } } }}'3)让我们检查一下是否设置了映射
curl -XGET 'http://localhost:9200/twitter/tweet/_mapping?pretty=true'
4)发布一些带有嵌套数据的推文
curl -XPUT 'http://localhost:9200/twitter/tweet/1' -d '{ "name": "Athena", "version": 1, "db": { "@type": "Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 64bit", "oracle_props": [ { "@name": "open_cursors", "@value": 4000 }, { "@name": "USER_ROLE_PRIVS_COUNT", "@value": 1 }, { "@name": "CREATE_PERMISSION", "@value": "Y" } ] }}'5)仅嵌套查询
curl -XGET localhost:9200/twitter/tweet/_search -d '{ "query": { "nested" : { "path" : "db.oracle_props", "score_mode" : "avg", "query" : { "bool" : { "must" : [ { "term": { "db.oracle_props.@name": "open_cursors" } }, { "range": { "db.oracle_props.@value": { "lte": 4000 } } } ] } } } }}';6)查询“雅典娜”和“ Oracle”
curl -XGET localhost:9200/twitter/tweet/_search -d '{ "query" : { "bool" : { "must" : [ { "match" : {"tweet.name" : "Athena"} }, { "match" : {"tweet.db.@type" : "Oracle"} } ] } }}'7)结合前两个查询
curl -XGET localhost:9200/twitter/tweet/_search -d '{ "query" : { "bool" : { "must" : [ { "match" : {"tweet.name" : "Athena"} }, { "match" : {"tweet.db.@type" : "Oracle"} }, { "nested" : { "path" : "db.oracle_props", "score_mode" : "avg", "query" : { "bool" : { "must" : [ { "term": {"db.oracle_props.@name": "open_cursors" } }, { "range": {"db.oracle_props.@value": { "lte": 4000} } } ] } } } } ] } }}'结果为
{ "took": 2, "timed_out": false, "_shards": { "total": 5, "successful": 5, "failed": 0 }, "hits": { "total": 1, "max_score": 2.462332, "hits": [ { "_index": "twitter", "_type": "tweet", "_id": "1", "_score": 2.462332, "_source": { "name": "Athena", "version": 1, "db": { "@type": "Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 64bit", "oracle_props": [ { "@name": "open_cursors", "@value": 4000 }, { "@name": "USER_ROLE_PRIVS_COUNT", "@value": 1 }, { "@name": "CREATE_PERMISSION", "@value": "Y" } ] } } } ] }}
