Crawler architecture in SharePoint 2007

Bill English has written a nice article about the architecture of crawler in SharePoint 2007.
Here is the link: http://admincompanion.mindsharp.com/BillBlog/Lists/Posts/Post.aspx?ID=83

Search results not generated even when contents are indexed

Background:
Search is configured on the MOSS Server and contents are indexed properly.
However no results are generated when user tried to find the data that exists on the site.

The users are using the URL http://sharepoint.domain.com/ to access the site at http://servername/

Cause:
Alternate Access Mapping (AAM) settings are not set properly.

Resolution:

1. Add http://sharepoint.domain.com/ URL in the default zone
2. Add http://servername/ in the intranet zone
3. Re-run the crawl

The results will be displayed to the users now.

Exchange Public Folders versus SharePoint

SharePoint Team's blog gives a comparison between the two and confirms that the public folders will be available in Exchange 2010 and will be supported till 2020.

CMS Assessment Tool

The CMS Assessment Tool helps a user to identify valuable information to plan for issues that might arise when he migrates an application from the MCMS 2002 platform to Office SharePoint Server 2007.

The tool gathers the following information:

1. Lists of template files and the which features they use. From this information, you can determine the level of effort required to migrate each template
2. Information about your current infrastructure. This information can help you determine whether that infrastructure can support a side-by-side installation of MOSS
3. The tool lists characteristics that are not supported in SharePoint Server 2007
4. Statistics about your MCMS users and roles, resources, channels, and postings

Points to note:

1. The CMS Assessment Tool analyzes and reports only on managed code
2. The CMS Assessment Tool is a read-only tool
3. Must be installed on the server where MCMS is installed
