The vector-search guides do not clearly explain when to use Auto, search effort or a fixed probe count. They also describe `minimum_nprobes` as the exact starting count, although Auto can search more partitions from the start. Explain how to choose public query controls for recall and latency, with short executable examples. Clarify that probe limits apply per segment, calibration targets are not recall guarantees, and more probes cannot remove quantization error. Keep necessary client/server version guidance in a short note. Validation: - The existing example test passes against published `lancedb==0.41.0`, covering all four snippets, result counts, filtering, finite distances and recall against an exact cosine query. The test body takes 0.20 s. Generated snippets match their source. - Vale reports no findings on added prose. Changed-function Python formatting and `git diff --check` pass. Repository-wide Ruff has 137 findings identical to the previous scan, including seven pre-existing findings in the example file. - Mint 4.2.888 strict validation reports the same four `RsExampleBody`/`RsExampleTail` import warnings as pristine base `0b20965d`, with no additional warnings.
