IFilter for Help files
This IFilter allows any 3rd-party application relying on IFilters to index the content of Help files (.HLP).
The Citeknet HLP IFilter is specially designed and optimized to use the extra indexing feature included with Windows Desktop Search, Microsoft SharePoint Portal Server or Microsoft SQL Server.
System requirements: Windows 2000, Windows XP, Windows Server 2003 or later...
Note: It is highly recommended to have a RTF IFilter installed to fully index the text contained in HLP files. Check the Channel9 page if you need to download one.
