Two "empty" mappings reported differently in field_caps #107031
Description
Description
The first index has in its request body the mappings and properties elements, while the second one has an empty JSON body.
The _field_caps for the first index returns the metadata fields, while for the second index it returns nothing. From my point of view there is no difference between these two indices when it comes to their mappings, so the output of field_caps should be consistent.
This was tested with Postman REST client with main code from few days ago.
PUT /localhost:9200/test1
{
"mappings": {
"properties" : {
}
}
}
POST /localhost:9200/test1/_field_caps?fields=*
{
"indices": [
"test1"
],
"fields": {
"_routing": {
"_routing": {
"type": "_routing",
"metadata_field": true,
"searchable": true,
"aggregatable": false
}
},
"_doc_count": {
"integer": {
"type": "integer",
"metadata_field": true,
"searchable": false,
"aggregatable": false
}
},
"_index": {
....
now, another "empty" index:
PUT /localhost:9200/test2
{}
POST /localhost:9200/test2/_field_caps?fields=*
{
"indices": [
"test2"
],
"fields": {}
}
