IFilter replacement

I am currently using IFilters to extract text from different files (word, excel, tiff, pdf, etc.). I understand that IFilters were discontinued with Windows 8. Does anyone have any recommendations on how to extract text without embedded applications? If it is used, I use C # and .Net 4

IFilter does not stop. Only the Windows Indexing service is terminated in favor of Windows Search or Microsoft Search Server. Both continue to use IFilters.

According to this documentation , the future compatibility issue for IFilters in the future is support for the IPersistStream interface. All modern implementations should avoid using IPersistStorage , so they do not need to access the drive itself.

Can you follow Microsoft recommendations?

From Deploying IFilter Indexing Services :

Indexing is no longer supported with Windows XP and is not available for use with Windows 8. Instead, use Windows Search for the client-side search and Microsoft Search Server Express for server-side searches.
