`POST /memories/search`

Search the user's knowledge graph for relevant facts and entities.

Uses hybrid retrieval (BM25 + cosine + graph traversal + cross-encoder
reranking) to find the most relevant memory edges.

## Authentication

- `HTTPBearer`, http, header `Authorization`

## Header parameters

- `X-On-Behalf-Of` (`search_memories.header.X-On-Behalf-Of`; any of, optional)
  - any of: `string`, `null`
- `X-External-User-Id` (`search_memories.header.X-External-User-Id`; any of, optional)
  - any of: `string`, `null`
- `X-App-Id` (`search_memories.header.X-App-Id`; any of, optional)
  - any of: `string`, `null`

## Request body

_Required._

- `query` (`search_memories.query`; string, required)
  - minLength 1; maxLength 5000
- `agent_id` (`search_memories.agent_id`; string, required)
- `max_results` (`search_memories.max_results`; integer, optional)
  - min 1; max 50; default `10`
- `created_after` (`search_memories.created_after`; any of, optional) — Only return memories created after this datetime
  - any of: `string`, `null`
- `created_before` (`search_memories.created_before`; any of, optional) — Only return memories created before this datetime
  - any of: `string`, `null`
- `graph_ids` (`search_memories.graph_ids`; any of, optional) — Shared knowledge graphs to blend into the search alongside the user's own memory. Results from these come back tagged scope="graph" with their graph_id.
  - any of: `array<string>`, `null`
- `visibility` (`search_memories.visibility`; any of, optional) — Optional. Keep only facts whose both endpoint nodes carry this visibility — 'public' therefore returns facts that expose no private node, which is what makes them safe to surface outside the owner's private view. Omit for no visibility filtering. Every result reports source_visibility and target_visibility regardless, so you can filter on your own terms instead.
  - any of: `string`, `null`
