One that is well-formed but names no bundle returns unknown_bundle listing every valid one; anything else, invalid_input. Pages are included whole, in order, while the document fits in 60 KiB; a page that does not fit is listed by path under More pages rather than cut, except a first page too big on its own, which is cut at a paragraph and ends with a link to the full page. Pages are read from the live docs site; no key or account is needed. A built bundle is served for 10 minutes, then refreshed in the background. A page that cannot be loaded does not fail the call: the previous bundle, or a partial one naming the pages it lacks, is served instead, and backend_unavailable is returned only when no page loads and nothing is cached yet.",

For a query of 4 to 8 distinct keywords, pages missing one incidental keyword join the ranking at half weight, which is how an API renamed between versions is still found; a platform or language word is never the one dropped. Without the version filter, current-version pages lead, and each result reports isCurrent plus a version label when the page is versioned; the filter restricts results to pages carrying that label, so unversioned pages such as the REST API reference are excluded. limit caps the rows returned, never the totalAvailable count, and there is no offset.\n\nResults come from a snapshot of the documentation repository, rebuilt periodically, so a page published since the last rebuild is missing until then; fetch_cometchat_doc_page reads the live site. Errors: invalid_input for a malformed argument, backend_unavailable when the index cannot be read.

Quotes and operators such as OR have no special meaning, and common words such as \"how\", \"is\" and \"can\" are not counted as keywords.
