Doc-values-only search on numeric, date, keyword, ip, and boolean fields
editYou can now run term and range queries on numeric, date, date_nanos,
keyword, ip, and boolean fields that only store doc values.
In exchange for slower queries, doc-value-only fields offer:
- Increased indexing rates
- Better storage efficiency
- Great performance for aggregating and sorting data
For more information about doc values, refer to the
doc_values mapping parameter documentation.
