Elasticsearch version (bin/elasticsearch --version): 7.14.0 (docker)
Everything works on 7.13.4.
Plugins installed: []
JVM version (java -version): whatever comes with the docker container
OS version (uname -a if on a Unix-like system):
Linux yrodiere.redhat 5.13.6-200.fc34.x86_64 #1 SMP Wed Jul 28 15:31:21 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
Description of the problem including expected versus actual behavior:
Given this mapping:
{
"mappings": {
"properties": {
"mynested": {
"type": "nested",
"properties": {
"mykeyword": {
"type": "keyword",
"doc_values": "false"
}
}
}
}
}
}The following search query will never match on ES 7.14.0, regardless of the content of the index:
{
"query": {
"nested": {
"path": "mynested",
"query": {
"exists": {
"field": "mynested.mykeyword"
}
}
}
}
}It used to match on ES 7.13.4 (and many previous versions).
Enabling doc_values makes it match again. Removing the "nested" query around the "exists" query makes it match again.
Steps to reproduce:
curl -XPUT -H "Content-Type: application/json" 'localhost:9200/test/' -d'{"mappings": {"properties": {"mynested": {"type": "nested", "properties": {"mykeyword": { "type": "keyword", "doc_values": "false" } } } } } }'
curl -XPUT -H "Content-Type: application/json" 'localhost:9200/test/_doc/1' -d '{"mynested": { "mykeyword" : "present" } }'
curl -XPOST -H "Content-Type: application/json" 'localhost:9200/test/_search' -d '{"query": { "nested": { "path": "mynested", "query": { "exists": { "field" : "mynested.mykeyword" } } } } }'Results on 7.14.0:

}
}
]
}
