-## Searching shared history
-
-Zulip's [channel permissions](/help/channel-permissions) model allows access to
-the full history of public channels and private channels with shared history,
-including messages sent before you joined the channel (or organization), or those
-sent to public channels you are not subscribed to.
-
-By default, Zulip searches messages in your history, i.e., the
-messages you actually received.  This avoids cluttering search results
-with irrelevant messages from public channels you're not interested in.
-
-If you'd like to instead search the organization's shared history, any query
-using the `channel:` or `channels:` filters will search all messages that you have
-access to in the selected channel(s).  For example:
-
-* `channels:public logo`: Search for `logo` in all public channels in the
-  organization.
-* `channels:public sender:Elena García`: Search for all messages sent by
-  Elena to any public channel.
-* `channel:design logo`: Search for the word `logo` in all messages sent to
-  **#design**, regardless of whether you were subscribed at the time the message
-  was sent.
