Best match puts all-term matches before partial matches and related reading. Identical social posts and matching long titles across other sources are grouped when access is the same. Search covers published titles, descriptions, available article text, report overviews, and the full text of the nutrient, gene and learning-essential reference pages. Books, uploaded chapters and downloads-page reports are searchable through selected editorial guides and topic names; the original files and full book text are not published. Full Drive reports are not copied into search. Substack subscriber titles and public summaries are included; full subscriber content opens on Substack. Video transcripts are added when available.
