# searchPlainHelpCenter

> Perform a semantic (vector) search across Plain's own public help center (help.plain.com).
Available to every workspace's Sidekick so it can answer questions about how Plain itself works.
Read-only and hard-restricted to Plain's public product documentation; it never returns the
caller's own data or any other workspace's content. Returns up to `pageSize` results
(default 10, max 50) ranked by relevance.
