Assume that you use the Multi-Mailbox Search feature to perform a discovery search in a Microsoft Exchange Server 2010 environment. The search keywordscontain multiple logical operators, such as OR and AND. In this situation, the Multi-Mailbox Search feature returns incorrect results.
For example, a search for the keyword "WordA" returns 344 items and a search for "WordA AND WordB" returns 31 items. However, a search for "(WordA AND WordB) OR WordA OR WordB" also returns 31 items incorrectly.
