others. A quirk in Zulip's current implementation means that if all of your
keywords are ignored, we'll return 0 search results.
## Other notes
## Messages sent before you joined
* By default, search only displays messages that you actually
received. However, if your search is restricted to a stream where you have
[access to stream history](/help/stream-permissions), you can search for
messages from before you subscribed to the stream (or even joined your
Zulip organization).
In most cases, Zulip only searches messages that you received. In particular,
this means Zulip will not search messages sent before you joined.
* To see the list of search operators in-app, click the **gear** (<i
class="fa fa-cog"></i>) icon in the upper right, and select
**Search operators**.
However, if a) the search includes a `stream:` operator and b) that stream
is either public or [private with shared history](/help/stream-permissions),
Zulip will search the entire history of the stream, including messages
that were sent before you joined.
