Outlook’s Search function integrates with the Windows Search Indexer of Windows. As this is an indexed search, it allows for faster search query results than with the traditional built-in Search function in Outlook.
With this integration, you also have access to a lot of special search commands and index fields to refine your search.
While many of the commands and fields can also be found and selected directly within Outlook, not all of them are exposed. Additionally, you’ll have to type these commands or field names manually when searching for Outlook content via the Windows Search box outside of Outlook.
This is a reference guide to the available search operators and search fields and how to use them.
