collect

@Experimental
public static CollectReducer collect()

REDUCE COLLECT — gather per-document projections within a GROUPBY group.

Returns a CollectReducer builder; configure projected fields via fields(...) or fieldsAll(), then optionally chain sortBy(...) and limit(...) before calling Reducer.as(String).

Experimental. Both the underlying Redis Search feature and this API may change. Before issuing COLLECT queries the server must be configured with CONFIG SET search-enable-unstable-features yes; otherwise the server returns SEARCH_QUERY_BAD `COLLECT` is unavailable when `ENABLE_UNSTABLE_FEATURES` is off.
