Answer 1

curl -X PUT "elasticsearch:9200/my_index?pretty" -H 'Content-Type: application/json' -d' { "mappings": { "my_index": { "properties": { "status_code": { "type": "string", "index": "not_analyzed" }, "session_id": { "type": "string", "index": "not_analyzed", "doc_values": false } } } } }

响应 curl "elasticsearch:9200/my_index/_mapping?pretty" { "my_index" : { "mappings" : { "my_index" : { "properties" : { "session_id" : { "type" : "string", "index" : "not_analyzed", "doc_values" : false }, "status_code" : { "type" : "string", "index" : "not_analyzed" } } } } } }

doc_values默认为true。在这种情况下未显示。但是显示doc_values == false。
