Hello,
When working with my dashboards I got this error message:
"Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default. Please use a keyword field instead. Alternatively, set fielddata=true on [rule.id] in order to load field data by uninverting the inverted index. Note that this can use significant memory."
I try to update that field with:
PUT my-index/_mapping
{
"properties": {
"rule.id": {
"type": "keyword",
"fielddata": true
}
}
}
I got as a result:
{
"error" : {
"root_cause" : [
{
"type" : "mapper_parsing_exception",
"reason" : "unknown parameter [fielddata] on mapper [id] of type [keyword]"
}
],
"type" : "mapper_parsing_exception",
"reason" : "Failed to parse mapping [_doc]: unknown parameter [fielddata] on mapper [id] of type [keyword]",
"caused_by" : {
"type" : "mapper_parsing_exception",
"reason" : "unknown parameter [fielddata] on mapper [id] of type [keyword]"
}
},
"status" : 400
}
I checked and this field's type is text, keyword.
Is that the reason I cannot update the fielddate to true?
Any ideas how to solve that?
Regards,
P
