…nd custom index names - Replace Search Configuration bullets with markdown tables covering core knobs and per-index-type nprobes guidance - Document minimum_nprobes / maximum_nprobes with a note on adaptive partition scanning under filtered queries - Add Advanced Search Controls subsection covering distance_range() for thresholded retrieval and bypass_vector_index() for recall measurement against flat-scan ground truth - Document that vector indexes support custom names via name=..., clarifying that the _idx suffix is a default convention - Add four runnable pytest snippet tests backing the new examples Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
