How to search PDF in new IIS RRS feed

  • Question

  • User-773169280 posted


    The old IIS had the index search feature. PDFs can be searched by creating a catalog.

    However the latest IIS disabled this function.

    What bypass can be done?

    What do you mean by "disabled" ?

    Historically, pdf documents have not been indexed for IIS/Search unless you've installed a pdf iFilter which is not included with IIS.

    If you're moving to a new version of IIS / New server, make sure you install a pdf iFilter

    Thank you Mike.

    I might not clarify it. Our website has used the classic ASP and Indexing Service to search PDF by creating a catalog. Since the old IIS has the Indexing Service feature that created index and searches against a specific catalog. But the Windows/IIS was now upgraded, Indexing Service is deprecated in the new Windows/IIS. It is replaced by Windows Search Service.

    1, Is there any way to still use the Indexing Service in the new Windows/IIS?

    2, If I have to use Windows Search Service, how to migrate from Indexing Service to Windows Search Service. The code used for Indexing Service  can be used for Windows Search Service?

    Thank again,

    Thank you Able for the informative link.
    The following link also addresses the issue, but looks like there is no solution.

    By the way, our website has a lot of class ASP pages that uses Indexing Service to search PDF. The IIS upgrading leads to the replacement of Indexing Service with currently unknown avenue.  Apparently it is a big job to be done.
