=== Field Data Fields
|
|
|
|
Allows to return the <<fielddata,field data>> representation of a field for each hit, for
|
|
example:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
GET /_search
|
|
{
|
|
"query" : {
|
|
"match_all": {}
|
|
},
|
|
"fielddata_fields" : ["test1", "test2"]
|
|
}
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
|
|
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.
