 ### Required query parameters
 
 - `pool`: id of the VRCUrl pool, only letters numbers hyphens or underscores, optionally followed by an integer for pool size.

+- `input`: youtube search query. All chars up to and including this exact unicode char `→` are ignored, and then whitespace is trimmed. THIS MUST BE THE LAST QUERY PARAMETER AS ALL CHARS AFTER IT ARE CAPTURED VERBATIM (so you can type & etc without encoding). If this contains a url with a playlist ID, playlist results will be loaded instead (which is a bit different, up to 100 results and no descriptions).
 
 ### Optional query parameters
 
 - `thumbnails`: set to `1`, `true`, `yes`, `on` or whatever to load thumbnails
 - `icons`: set to `1`, `true`, `yes`, `on` or whatever to load channel icons
-- `captions`: set to `1`, `true`, `yes`, `on` or whatever if you need access to closed captioning data
+- `mode`: If set to `latestontop` will search without filter to include the "Latest from ..." section (if it exists). Otherwise it uses search filter for Videos only sorted by Relevance.
+- `bp`: Custom YouTube search filter. Go to youtube search site and set some filters and you will see the corresponding `bp` value in the URL. Overrides `mode` option. Use at your own risk (experimental).
