Hello I need to use the top hits aggregation [http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations-metrics-top-hits-aggregation.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations-metrics-top-hits-aggregation.html) for a grouping feature. The aggregation should be applied on nested fields. e.g. My nested field is F with path P. Would appreciate it if someone can share an example to create a top hits aggregation query for this scenario.

Hi, In that case you would need to wrap a terms agg in a nested aggregation (with the desired path) and a top\_hits inside that terms aggregation. Unfortunately the top\_hits aggregation doesn't yet work inside a nested aggregation. However work is being done that will add this support: > > > At the moment the \`top\_hits\` aggregation fails if it is being put in a nested or… reverse\_nested aggregations. This PR add proper support for nested inner objects being emitted as hits in the \`top\_hits\` aggregator. All the known fetch phase features are supported. > > This PR adds fetch infrastructure to get #3022 in as well.
