Match document if it contains multiple nested documents in elasticsearch - elasticsearch

Question

I have a document that contains arrays of nested documents. I have a requirement to return matches if the document contains all of the specified nested documents.
here is the relevant part of the mapping:
"element": {
"dynamic": "false",
"properties": {
"tenantId": {
"type": "string",
"index": "not_analyzed"
},
"fqn": {
"type": "string",
"index": "not_analyzed"
},
"id": {
"type": "string",
"index": "not_analyzed"
},
"name": {
"type": "string",
"index": "not_analyzed"
},
"type": {
"type": "string",
"index": "not_analyzed"
},
"location": {
"type": "string",
"index": "not_analyzed"
},
"tags": {
"type": "nested",
"properties": {
"id": {
"type": "string",
"index": "not_analyzed"
},
"dataSourceId": {
"type": "long",
"index": "not_analyzed"
},
"name": {
"type": "string",
"index": "not_analyzed"
},
"value": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
}
The goal is to be able to return elements that contain all of a list of tags (although the element is permitted to contain additional tags beyond the search requirement).
Here is what I have so far:
{
"query": {
"bool": {
"filter": {
"nested": {
"path": "tags",
"query": {
"bool": {
"must": [
{
"bool": {
"must":{
"term": { "tags.name": "name1" },
"term": { "tags.value": "value1" }
}
}
},
{
"bool": {
"must":{
"term": { "tags.name": "name2" },
"term": { "tags.value": "value2" }
}
}
}
]
}
}
}
}
}
}
}
The problem with this approach is that it returns 0 hits with multiple tag values (it works fine for a single value). I believe that this is because the query is requiring that a tag have multiple names and values in order to match, which obviously can't happen. Does anyone know how to query for elements that contain all of a list of tags?
edit: this is using elasticsearch 5.0

Answer 1

We figured it out. The answer was to create two nested queries, instead of having two clauses to the same nested query.
{
"query":{
"bool":{
"must":[{
"nested":{
"path":"tags",
"query":{
"bool":{
"must":[
{"term":{"tags.name":"name1"}},
{"term":{"tags.value":"value1"}}
]
}
}
}
},
{
"nested":{
"path":"tags",
"query":{
"bool":{
"must":[
{"term":{"tags.name":"name2"}},
{"term":{"tags.value":"value2"}}
]
}
}
}
}]
}
}
}
