让我们开始吧：
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"
}
]
}
}
}
]
}
}
