==== Significant terms on numeric fields
|
|
|
|
Numeric fields have been refactored to use a different data structure that
|
|
performs better for range queries. However, since this data structure does
|
|
not record document frequencies, numeric fields can no longer be used for
|
|
significant terms aggregations. It is recommended to use <<keyword,`keyword`>>
|
|
fields instead, either directly or through a <<multi-fields,multi-field>>
|
|
if the numeric representation is still needed for sorting, range queries or
|
|
numeric aggregations like
|
|
<<search-aggregations-metrics-stats-aggregation,`stats` aggregations>>.
