Returning only aggregation results
editReturning only aggregation results
editThere are many occasions when aggregations are required but search hits are not. For these cases the hits can be ignored by
setting size=0
. For example:
GET /twitter/_search { "size": 0, "aggregations": { "my_agg": { "terms": { "field": "text" } } } }
Setting size
to 0
avoids executing the fetch phase of the search making the request more efficient.
