Elasticsearch documentation states that doc\_counts are approximate and we are seeing count discrepancies in our aggregations. This is a big issue for our customers How can we improve the accuracy of the doc\_count in nested documents?

Elasticsearch v6.1.1

Following is my search query:  
{  
"from": 0,  
"size": 10,  
"query": {  
"bool": {  
"must": [  
{  
"query\_string": {  
"query": "\*"  
}  
},  
{  
"siteGuid.keyword": "d4908c7d-fc14-4aaf-b85d-8dc1bafd7cfd"  
}  
}  
]  
}  
},  
"aggs": {  
"--CUSTOM--": {  
"nested": {  
"path": "binning.binningSets"  
},  
"aggs": {  
"--Binning--": {  
"terms": {  
"field": "binning.binningSets.label",  
"size": 100,  
"order": { "\_key" : "asc"}  
},  
"aggs": {  
"--Bin Set--": {  
"nested": {  
"path": "binning.binningSets.bins"  
},  
"aggs": {  
"--Bins--": {  
"terms": {  
"field": "binning.binningSets.bins.token",  
"size":100,  
"order": { "\_key" : "asc"}  
}  
}  
}  
}  
}  
}  
}  
}  
}  
}

Thank you!
