Recently I ran across a scenario where a company had migrated from Exchange 2003 to Exchange 2007 and noticed that their Search functionality was behaving differently. They, like most, used their email as a major component of their business. Work orders would come into their mailboxes and they would use Search to find and manage the flood of inbound emails. Each email would have a subject pattern that was somewhat predictable based on their work ordering numbering scheme. When they would search they would search for their portion of the code. This portion was not always the first portion of the string of characters. When using Exchange 2003 this worked great. Once they moved to Exchange 2007, they got inconsistent results. Why? Answer

Search in Exchange 2007 (Exchange Search) is completely different from earlier versions of Exchange. Improvements were made to performance, Content Indexing, and Search. New items are indexed almost immediately after their arrival into a mailbox giving end users a fast, reliable, and more stable search function. In Exchange 2000 and Exchange 2003, indexing was not enabled by default.
