Microsoft Exchange 2007 Search Basics

Unlike Exchange 2003, Exchange Search is enabled by default in Exchange 2007 and is automatically applied to new databases as they are created. Exchange Search depends on a full-text indexing and each mailbox database in Exchange 2007 has a full-text index associated with it. However, this latest incarnation of Exchange server-side search not the status quo. Search for Microsoft Exchange 2007 has been rewritten. 

Indexing content is now performed as messages arrive at the store and not on a set schedule. Certain attachment types are also indexed, most notably Word, Excel, PDF, PowerPoint and HTML files. To facilitate these changes, indexing is now more integrated with the Information Store Service. The result has been much improved indexing performance in Exchange 2007.

Exchange 2007 Search will show a few processes in Task Manager:

  • Microsoft.Exchange.Search.ExSearch.exe (MSSearch)
  • Msftefd.exe (filter daemon - similar to SQL Server 2005)
  • Msftesql.exe (core indexer)

These Exchange 2007 Search processes will throttle server-side full-text indexing when the Exchange Server needs resources for client access so the user experience is not negatively impacted. Otherwise, new messages get indexed within seconds of arrival. Searches using the server-side Exchange 2007 Search return results expeditiously.

Exchange 2007 Search is not the same as Instant Search in Outlook 2007, which is implemented with Windows Desktop Search (WDS) on the client. Outlook 2007 Instant Search requires either a .pst or Exchange cached mode (.ost). For the desktop client to benefit from Exchange 2007 Search they need to use either Outlook Web Access or a MAPI profile without Exchange cached mode (online mode).

Even though they are index-enabled by default, some databases may not need to be searched efficiently and therefore do not require an index. Full-text indexing is toggled on or off ($true or $false) from the Exchange Management Shell as follows:

>Set-MailboxDatabase <MailboxDatabaseName> -IndexEnabled $false

Also using PowerShell, the Test-ExchangeSearch cmdlet is used to verify the status of Exchange 2007 Search by creating a message and querying for that message and reporting back to the administrator.

In-house application support. Should a third-party application be in-place which integrates or uses Outlook for mail services, the application would need to be developed in order for it to be able to use Google Mail

Posted by: Promotional Products at May 13, 2010 2:20:13 PM

Well, it's very important to emphasise that flexibility is the key with Exchange. Google's mail offering may at first glance appear to be ‘cheap’, when compared to similar Exchange hosted offerings, and also, to running Exchange ‘in-house,’ but it is nowhere near as feature rich and flexible as Exchange.

Dogs just faithfully sit like statues without blinking---staring at you enjoying that steak or hot dog---so much hoping you'll break down and give them a nibble of it. And we sometimes cave in and give them something---but we later regret it when they get sick.

If you are looking in a specific community, contact the Board of Realtors there and ask if there is a way you can access the information in their MLS system. Some Realtors have websites where you can search the system for very specific things just like they can for their clients.
