Field Data Fields
editField Data Fields
editAllows to return the field data representation of a field for each hit, for example:
{ "query" : { ... }, "fielddata_fields" : ["test1", "test2"] }
Field data fields can work on fields that are not stored.
It’s important to understand that using the fielddata_fields
parameter will
cause the terms for that field to be loaded to memory (cached), which will
result in more memory consumption.
