Overview
Metadata in OpenSearch refers to additional information stored for each document. This is achieved using the specific metadata fields available in OpenSearch. The default behavior of some of these metadata fields can be customized during mapping creation.
Examples
Using _meta meta-field for storing application-specific information with the mapping:
PUT /my_index?pretty
{
"mappings": {
"_meta": {
"domain": "security",
"release_information": {
"date": "18-01-2020",
"version": "7.5"
}
}
}
}Notes
- Meta fields available include: _index, _type, _id, _source, _size, and _field_name.
