feat: support distinct in federated search - #972
Conversation
📝 WalkthroughWalkthroughAdds ChangesFederation search options
Estimated code review effort: 1 (Trivial) | ~3 minutes Merge Risk: 🔵 Low · up to Federated search now supports serializing distinct in requests, but the class’s JSON-like string representation still omits distinct and showPerformanceDetails. This does not affect request behavior, but should be corrected as a bounded follow-up before treating the change as fully complete. Poem

toString()omitsdistinct(and other federation fields), so serialized output is incomplete.On Line 49, the JSON only includes
limit/offset. After addingdistinct, this method now returns incorrect federation JSON for any caller usingtoString().Suggested fix
`@Override` public String toString() { JSONObject jsonObject = - new JSONObject().put("limit", this.limit).put("offset", this.offset); + new JSONObject() + .put("limit", this.limit) + .put("offset", this.offset) + .put("mergeFacets", this.mergeFacets) + .put("facetsByIndex", this.facetsByIndex) + .put("distinct", this.distinct); return jsonObject.toString(); }🤖 Prompt for AI Agents

MultiSearchFederation gained showPerformanceDetails on main while this branch added distinct. The setter conflict cut through a method whose closing 'return this;' both sides shared, so it is resolved as two complete setters rather than one with two signatures.

Include the new fields in MultiSearchFederation.toString().
toString() documents a JSON representation but serializes only limit and offset, so it drops distinct and showPerformanceDetails. The Client.multiSearch request path uses JsonHandler, not toString(), so request serialization is not affected. Add a toString() regression test if this representation is supported.
