This allows the server to filter messages based on a text query, and even on their type, and this feature is often used by graphical clients to implement features like the chat gallery, chat profile pictures and more.
Available filters:
The returned messages.Messages constructors contain parameters for pagination, the messages themselves and two offset_id_offset/count parameters that can be used to display a progress/total counter like photo 134 of 200.
For example, when displaying the chat photo gallery, we could display a photo ${offset_id_offset} of ${count} indicator on top.

channels.getChannelRecommendations#25a71742 flags:# channel:flags.0?InputChannel = messages.Chats;The global search view should be split into two tabs, a "Chats" tab (containing results from all private/secret chats, private/public groups, private/public channels), and a "Channels" tab (containing results from private/public channels) only.
The "Chats" is split in the following sections:
Frequent contacts: Contains avatars and names of the most frequently used users, sorted as specified here ». Recent: Contains avatars and names of the most frequently used peers (users+chats+channels), sorted as specified here ». Searching when in the "Chats" tab should invoke messages.searchGlobal, replacing the previously mentioned sections with a list of peers (avatar+name+returned message, max one row per peer).
The "Channels" tab is split in the following sections:
Channels you joined: Contains avatars and names of the most frequently used channels, sorted as specified here ». Similar channels: Contains avatars and names of recommended public channels, similar to the ones the current user has already joined, fetched using channels.getChannelRecommendations without setting the channel flag, see here » for more info. Searching when in the "Channels" tab should invoke messages.searchGlobal with the broadcasts_only flag set, replacing the previously mentioned sections with a list of peers (avatar+name+returned message, max one row per peer).
