`docs/src/python/python.md` is the whole Python API reference, but it is maintained by hand and had drifted from the public API. Anything not listed there simply doesn't get rendered, so a number of public, documented, tested APIs were invisible to users — most notably branch management, where `diff` and `merge` live. I audited every public symbol reachable from `lancedb` and its subpackages against the `:::` directives on the page. This adds the missing ones: - **Branching** — `Branches`, `AsyncBranches` (`list` / `create` / `checkout` / `delete` / `diff` / `merge`) - **Tables** — `TableStatistics` (returned by `Table.stats()`; the fragment-level stats classes were already listed) - **Full text queries** — `FullTextQuery`, `MatchQuery`, `PhraseQuery`, `BoostQuery`, `MultiMatchQuery`, `BooleanQuery`, `FullTextOperator`, `Occur` - **Querying** — `LanceEmptyQueryBuilder`, `LanceTakeQueryBuilder`, `AsyncTakeQuery` - **Indices** — `Fm` (the FM-index for substring search), `IndexConfig` - **Blobs** — `blob`, `BlobType`, `BlobFile` - **Namespaces** — `connect_namespace`, `connect_namespace_async`, and both namespace connection classes - **Remote config** — `TlsConfig`, `HeaderProvider`, `OAuthConfig`, `OAuthFlowType` - **Rerankers** — the `Reranker` base class plus `JinaReranker`, `RRFReranker`, `MRRReranker`, `AnswerdotaiRerankers`, `VoyageAIReranker`, `WatsonxReranker` (5 of 12 were listed) - **Embeddings** — `get_registry`, `register`, and the 14 embedding functions that were missing (3 of 17 were listed) - **PyTorch** — `StreamingDataset` and the permutation API it is built on - **Misc** — `Session`, `tokenize`, `FtsToken`, `pydantic.Vector`, `pydantic.MultiVector`, `instrument_lancedb_metrics`, and the two exception types It also repairs cross-references in docstrings that no longer resolve: links into guide pages that have since moved to lancedb.com (`querying-an-ann-index`, `experimental-full-text-search`), `lance.dataset` references with no inventory behind them, and the relative targets `[Table](Table)` and `[PyArrow Table](pyarrow.Table)`. Deliberately left out: concrete implementation classes reached through their abstract base (`LanceTable`, `LanceDBConnection`, `RemoteDBConnection`), query base classes already covered by `inherited_members: true`, and internal plumbing such as `FullTextSearchQuery` and `ColumnOrdering`. ## Testing The docs job only runs on pushes to `main`, so I built the site locally and compared against a build of `upstream/main`: every added entry resolves, and no symbol that was rendered before stopped being rendered when the four packages moved to automodule. `mkdocs build --strict` exits 0 on this branch, against 61 warnings on `main`. ## Also in this PR `lancedb.index`, `lancedb.embeddings`, `lancedb.remote` and `lancedb.rerankers` are now rendered by a single mkdocstrings directive each, driven by the module's `__all__`, rather than a hand-maintained list. These four are where most of the drift was, and `__all__` is harder to forget than a docs page. `lancedb.embeddings` had no `__all__`; without one mkdocstrings renders no members at all for a re-export package, so one is added. AGENTS.md gains a section on how the page is wired up and how to build the docs locally. Rendering all that code for the first time surfaced ~100 more build warnings, which would have made #3707 (turning on `mkdocs build --strict`) harder to land, so the warning backlog is cleared here too. 97 of the 158 warnings were one systematic false positive — griffe cannot see the generated `__init__` of a pydantic dataclass, so every documented parameter looks unknown — switched off via `warn_unknown_params`. The remaining 61 came from 15 docstrings with real bugs: prose trailing a `Parameters` section (we were rendering parameters called `The`, `you` and `To`), types dropped because numpydoc needs spaces around the colon, `num_partitions, default sqrt(num_rows)` parsing as a list of names and inventing a `default` parameter, and one parameter indented five spaces. `mkdocs build --strict` now exits 0. --- #3747 (the coverage test that keeps this from happening again) is stacked on this branch, so review it after this one. --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>
The Multimodal AI Lakehouse

The ultimate multimodal data platform for AI/ML applications.
LanceDB is designed for fast, scalable, and production-ready vector search. It is built on top of the Lance columnar format. You can store, index, and search over petabytes of multimodal data and vectors with ease. LanceDB is a central location where developers can build, train and analyze their AI workloads.
Demo: Multimodal Search by Keyword, Vector or with SQL
