Only these types are ever in site search: pages, blogs, blog posts, FAQ questions, product descriptions, and books with their units and pages. Books joined the list after release 2026.8.1, so a site on that release or an earlier one never shows a book or a book page in search. A custom entity record or a form never appears, however it is set up. A record of those types is indexed only when it is published, its SEO robots setting allows indexing, and a signed-out visitor may read it, so members-only content is never in site search. Indexing runs in the background: seconds on a quiet site, minutes during a reindex or a large import. Still missing after that: it was saved by a background process (an asynchronous job or an import run on the server), which queues no indexing, so save it once in the admin; or it is found by its title but not by its words, because the layout areas holding them are not mapped to a search field. When the index itself is behind, Search › Indices has Reindex for each index; Rebuild empties the index before refilling it, so run that out of hours. The full checklist, with a URL that asks the index for one record, is in why a new record is not findable yet.
