We had an interesting use case from a customer. The customer used both Outlook and Notes to access different mail systems and wanted to be able to search both in one query. This can be done with EZ Notes Search and Windows Search.
The customer also wanted to be able to limit their search to either Notes or Outlook for some queries. They found you can filter your search results through the use of a query filter. For example, you can add store:EZN or store:MAPI to the query if you want to only search Notes or Outlook, respectively.
Note: Corrected the above on 12/05/2011. The qualifier is supposed to be "store", not "scope".
