The Documentation tab now reads as a manual over Python, TypeScript and SQL rather than a Python guide with SQL bolted on. Basics replaces the Catalog section: what the catalog holds, what each API surface can do, jobs, agentic skills, and what Lance is. Management is new and is the CRUD and listing reference for every catalog object, with a column per language so the gaps are visible -- TypeScript has no function or SQL methods, SQL needs a deployment. Search becomes Query and gains a SELECT reference, since an analytical query is a query whether it came from a builder or a statement. Jobs is new. Every long-running operation already returned the same handle from an _async method; nothing documented it. The SQL function reference gains what Lance registers on top of DataFusion: contains_tokens, backed by the FTS index, and the JSON accessors, backed by a JSON scalar index. Geospatial st_* functions are behind a build feature LanceDB does not ship, which is now stated rather than left to a confusing error. Removes the Geneva pages' orphaned snippets, merges FTS Examples into Full-Text Search, and splits Query Optimization into Explain and Explain Analyze.

### Slow or unexpected query results {#slow-or-unexpected-query-results}
|
|
|
|
If you have slow queries or unexpected query results, it can be helpful to
|
|
print the resolved query plan.
|
|
|
|
LanceDB provides two powerful tools for query analysis and optimization: `explain_plan` and `analyze_plan`.
|
|
|
|

|
### The Python multiprocessing module {#the-python-multiprocessing-module}
|
|
Multiprocessing with `fork` is not supported. You should use `spawn` instead.
