Queries on the Contents Property Do Not return Hits for MSG Files (277560)


The information in this article applies to:

  • Microsoft Windows 2000 Server
  • Microsoft Internet Information Services 5.0
  • Indexing Service
This article was previously published under Q277560

SYMPTOMS

If you index .msg files by using Indexing Service and query the files by using the contents property, you may not receive any hits in the result.

CAUSE

MSG files are binary files, which are associated with the binary Null IFilter in Indexing Service. The Null IFilter is not able to extract the textual information out of the .msg file. As a result, you do not get any results if you query the contents property.

STATUS

This behavior is by design.

MORE INFORMATION

In Windows NT Server 4.0, .msg files are processed by default with the Default IFilter if the Filter Files with unknown extensions option is configured in Index Server 2.0.

The Default IFilter extracts textual contents out of the .msg files. In this case, you get .msg files in your query results.

For Indexing Service, Microsoft recommends that you write a custom IFilter for .msg files. To do this, refer to the following section in the MSDN Library:
