Some type of query is always applied to produce the view that you see in the Zimbra interface. This topic describes in detail the search grammar used for Zimbra's Search feature & the most overlooked feature: The main search bar!
- TIP: You can set your General Options to 'Always show search string' to see the current query in the Search toolbar. For example, when this option is set, clicking your Inbox folder shows the query string 'in:inbox'.
