NOT operator search
The NOT operator can be inserted in between two search terms to specify that the first term must be present, and the second term must be absent. For example:

cloud NOT computing
Arctera Unified Platform also lets you begin a search with a NOT operator. For example:
NOT "cloud computing"
This search attempts to return every item that does not include the phrase cloud computing.
Note: Searches that begin with a NOT operator may fail to complete due to the large number of matching results, especially if you have a large message archive.
