ElasticSearch - Filter results by inner hits - elasticsearch

Question

We have a simple index of entities with mapping:
PUT resource/_mapping/entity
{
"properties": {
"id": {
"type": "keyword"
},
"name": {
"type": "keyword"
},
"claims": {
"type": "nested",
"properties": {
"claimid": {
"type": "keyword"
},
"priority": {
"type": "short"
},
"visibility": {
"type": "keyword"
}
}
}
}
}
Here's a sample document in the index:
POST resource/entity/
{
"id": "2",
"name": "e2",
"claims": [
{
"claimid": "c1",
"priority": "2",
"visibility": "M",
"reqid" : "2"
},
{
"claimid": "c2",
"priority": "1",
"visibility": "V",
"reqid" : "2"
},
{
"claimid": "c5",
"priority": "3",
"visibility": "H",
"reqid" : "2"
}
]
}
And a query to filter documents by provided set of 'claims.claimid', then to sort by 'claims.priority', select the one with highest priority and return only the 'claims.visibility' e.g.:
GET resource/entity/_search/
{
"query": {
"nested": {
"path": "claims",
"query": {
"bool": {
"must": [
{
"terms": {
"claims.claimid": [
"c1",
"c4",
"c5"
]
}
}
]
}
},
"inner_hits": {
"sort": [
{
"claims.priority": "asc"
}
],
"size":1,
"_source":{"includes":["claims.visibility"]}
}
}
}
}
And finally the problem to be solved: how to modify the query to filter out documents having resulted in "H" for visibility with highest priority in inner hits? Or what other query will return a set of documents with visibility of highest priority filtered by provided claim ids, but only those where visibility is not "H"?
A catch here is that we have to sort the documents having all types of visibilities and filter out those with resulting "H" on a complete list of results.
