Note

Indexing Service is no longer supported as of Windows XP and is unavailable for use as of Windows 8. Instead, use Windows Search for client side search and Microsoft Search Server Express for server side search.

 

Microsoft supplies several standard filters with Indexing Service. The following table lists the filter names, what they filter, and the DLL name. Selecting the name of a filter takes you to a description of the filter.

Filter Name Files Filtered Filter DLL
MIME Filter Multipurpose Internet Mail Extensions (MIME) mimefilt.dll
HTML Filter HTML 3.0 or earlier nlhtml.dll
Microsoft Office Document Filter Word, Excel, Microsoft PowerPoint offfilt.dll
Default or Plain Text Filter Plain text files - Default Filter Query.dll
