Since lancedb#4180, create_materialized_view runs the initial refresh before it returns (with_no_data=True skips it), so the page's first manual refresh now writes 0 rows, not 1. The example now reads the populated view and refreshes after a source change, and its snippets come from docs/web-tests/py/test_materialized_view.py. A note scopes the behavior: 0.39 and earlier create the view empty. Pages that said a refresh computes the rows now say it brings them up to date, and the SQL note no longer says an incremental refresh covers only added rows.
