Microsoft SharePoint(TM) Portal Server 2001 Resource Kit (Examples & Explanations Series)
Exchange 2000 Server integrates seamlessly with the Windows 2000 operating system. It is designed to meet the messaging and collaboration needs for businesses of all sizes. Together with its client software, Outlook 2000, Exchange provides a highly reliable, scalable, and easy-to-manage messaging and collaboration infrastructure.
If your primary need is to crawl e-mail messages, use Exchange 2000 Server. By using Exchange 2000 Server full-text search, servers can search messaging items in personal mailboxes and public folders to all users.
To aggregate searches from e-mail and other sources, use SharePoint Portal Server. However, SharePoint Portal Server does not support crawling private mailboxes.
Exchange 2000 Server uses the same search technology that SharePoint Portal Server uses. Exchange 2000 Server uses a version with proven clustering capability. The following list describes the components of Exchange 2000 Server.
- Data access. Data access is restricted to information stored in Exchange public folders and mailboxes.
- Filters. Exchange 2000 Server full-text search uses the MIME filter to crawl messaging items. Attachments are processed by using available filters according to their content type.
- Ranking. Exchange 2000 Server uses the same advanced probabilistic ranking algorithm that SharePoint Portal Server uses. This algorithm guarantees that Exchange 2000 Server returns the documents most relevant to a query at the top of the list of search results, providing increased user efficiency and satisfaction.
- Extensibility and programmability. Exchange 2000 Server uses the HTTPDAV protocol, specifically DASL, for searching.
- Query language. Full-text search in Exchange 2000 Server uses and supports SQL full-text extensions through the Distributed Authoring and Versioning (DAV) protocol. When using Exchange 2000 Server, Outlook Advanced Search takes advantage of Exchange 2000 Server full-text search. Exchange 2000 Server submits the natural language queries directly to the server. There is no client-side support for the SQL query language.
