Recalls the memories that best match a query, by hybrid full-text and vector search. With a publishable key, only the caller's end user's memories. A read with a request body, like a query.

**Not available yet.** Sylphx Agents is declared in the registry but no backend serves it: every call answers `501` with the problem code `UNIMPLEMENTED`.

- **Path** `POST https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/memory_stores/memory-store/memories:search`
- **Scope** `agents:sessions`
- **Effect** `read` — nothing is written.
- **Collection** [memories](/docs/api/memories)

## Request

| Field | Type | What it is |
| --- | --- | --- |
| `parent` | `string` | The memory store to search. Required. |
| `query` | `string` | What to recall, 1 to 2000 characters. Required. |
| `end_user` | `string` | Only memories about this end user. |
| `agent` | `string` | Only memories of this agent. |
| `page_size` | `int32` | At most this many; default 10, clamped to 100. |
| `page_token` | `string` | `next_page_token` of the previous page. |

## Response

| Field | Type | What it is |
| --- | --- | --- |
| `matches` | `MemoryMatch[]` | The matches, best first. |
| `next_page_token` | `string` | The token of the next page; empty on the last page. |

### MemoryMatch

| Field | Type | What it is |
| --- | --- | --- |
| `memory` | `Memory` | The memory. |
| `score` | `double` | The relevance, 0 to 1. |

### Memory

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/memory_stores/{memory_store}/memories/{memory}`. |
| `uid` | `string` | `mem_<cell><ulid>`; never reused. Output only. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `content` | `string` | The memory, at most 16 KiB of text. Required. |
| `end_user` | `string` | The end user it is about, for a store scoped to end users. |
| `agent` | `string` | The agent it belongs to, for a store scoped to agents. |
| `provenance` | `MemoryProvenance` | Where it came from. Output only. |
| `create_time` | `timestamp` | When it was written. Output only. |
| `update_time` | `timestamp` | When it was last changed. Output only. |

### ResourceMeta

| Field | Type | What it is |
| --- | --- | --- |
| `generation` | `int64` | Increases by one on every change to `spec`. Output only. |
| `etag` | `string` | Strong ETag (AIP-154): changes on any change to spec, status, or metadata. Send it back as `If-Match` or `etag` to make Update and Delete conditional; a mismatch fails with ABORTED / 409 `ETAG_MISMATCH`. Output only. |
| `create_time` | `timestamp` | When the Resource was created. Output only. |
| `update_time` | `timestamp` | When the Resource last changed. Output only. |
| `delete_time` | `timestamp` | Set while the Resource is being deleted. Output only. |
| `labels` | `map<string, string>` | Caller-writable, indexed labels (AIP-122 label rules). |

| `display_name` | `string` | Caller-writable human-readable name. |
| `creator` | `string` | The principal that created the Resource. Output only. |

### MemoryProvenance

| Field | Type | What it is |
| --- | --- | --- |
| `source` | `MemorySource` | Who wrote it. Output only. One of `agent`, `api`, `import`. |
| `session` | `string` | The session it was learned in, when an agent wrote it. Output only. |
| `event` | `string` | The event it was learned from, when an agent wrote it. Output only. |
| `principal` | `string` | The principal that wrote it, when a caller did. Output only. |

## Errors

- [`UNAUTHENTICATED`](/docs/api/errors/UNAUTHENTICATED) — No valid key or token was presented.
- [`PERMISSION_DENIED`](/docs/api/errors/PERMISSION_DENIED) — The key lacks the method's permission.
- [`RESOURCE_NOT_FOUND`](/docs/api/errors/RESOURCE_NOT_FOUND) — The named Resource does not exist or is not visible.
- [`INVALID_FIELD`](/docs/api/errors/INVALID_FIELD) — A field failed validation.

Every error arrives in the body [Errors](/docs/platform/errors) describes.
