# Migrate search to v5

> Upgrade search modes, filters, included context, defaults, and response readers

## Migration details

v5 searches one namespace, defaults to hybrid recall, and takes every option in one typed JSON body. Search has no query-string parameters.

### Request mapping

| Legacy | v5 |
| - | - |
| `containerTag` | `/ns/{namespace}` |
| body `q` | body `query` |
| body `limit` | body `limit` |
| `searchMode: "documents"` | `searchMode: "chunks"` |
| omitted search mode | `searchMode: "hybrid"` |
| `filters` | singular `filter` |
| `include.documents` or `.summaries` | `include.documents` |
| `include.relatedMemories` | `include.related` |
| `include.forgottenMemories` | `include.forgotten` |
| `rerank: true` / `aggregate: true` | `rerank: "order"` / `"aggregate"` |

<CodeGroup>
  ```bash Legacy theme={null}
  POST /v4/search
  {"q":"What did the user decide?","containerTag":"user_1","limit":10,"searchMode":"memories"}
  ```

  ```bash v5 theme={null}
  POST /ns/user_1/search
  {"query":"What did the user decide?","limit":10,"searchMode":"memories","threshold":0.6,"rewriteQuery":false}
  ```
</CodeGroup>

### Changed defaults

| Setting | v4 | v5 |
| - | - | - |
| Search mode | `memories` | `hybrid` |
| Similarity threshold | `0.6` | `0.3` |
| Reranking | Disabled | `rerank: "none"` |
| Query rewriting | Disabled | `false` |

Set mode and threshold explicitly while comparing versions. After parity testing, remove them only if you want the broader v5 hybrid defaults.

### Search modes

| Mode | Returns |
| - | - |
| `memories` | Formed memories only |
| `chunks` | Source chunks only |
| `hybrid` | Both result types in one ranked list |

Legacy `include.chunks` has no v5 equivalent. Choose `chunks` or `hybrid` instead.

### Included context and ranking

`include` is an object of booleans in the body, e.g. `"include": {"documents": true, "related": true}`. Each flag defaults to `false`.

* `include.documents` adds the most relevant source document to each result.
* `include.related` adds parent, child, and sibling memories.
* `include.forgotten` lets forgotten and expired memories appear in results, including as primary results.
* `rerank` accepts `none`, `order`, or `aggregate`; `rewriteQuery` controls retrieval-oriented query rewriting.

### Response mapping

| Legacy reader | v5 reader |
| - | - |
| Result array | `results` |
| Timing | `searchTime` |
| Source expansion | `result.included.document` |
| Related context | `result.included.related.{parents,children,siblings}` |
| Lifecycle fields | `result.system` |

Each primary result contains either `memory`, `chunk`, or both only if the contract allows it. Branch on field presence rather than assuming one result shape.

### Verification

* Compare IDs using explicit v4-equivalent defaults, then test v5 hybrid behavior separately.
* Cover all three modes, thresholds at `0` and `1`, each rerank option, and query rewriting.
* Cover every include alone and in combination, including empty results.
* Verify filters, namespace isolation, result limits, and invalid body/query placement.
