There 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.
