The search box in the header and the /search?q=... address look through the title, excerpt and text of published (date reached) pages and posts. Minimum 2 characters, at most 30 results; the search page is hidden from search engines (noindex). Drafts and future-dated items are never found.
/feed.xml — the latest 20 published posts (RSS 2.0). It is announced in the page <head> automatically and there is an "RSS" link in the footer.
Admin → Users → Download CSV: accounts matching the current search/status filter (id, name, e-mail, role, status, dates). Password hashes are never exported. Values starting with =, +, -, @ get a ' prefix so Excel does not run them as formulas. The export contains personal data — store the file safely.
