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.
