Indexing PDF files is not supported in Azure App Service environment

  • Description

    The following exception is thrown in the Azure App Service environment when indexing the content of a media item, which contains a blob with PDF file:

    ERROR Could not compute value for ComputedIndexField: _content for indexable: sitecore://master/{8EEE161B-F7D1-4339-AE77-1FA10B8CF8D2}?lang=en&ver=1
    Exception: System.Runtime.InteropServices.COMException

    The current implementation of the media indexing feature is based on IFilters, which are not supported in Azure App Service environment. To avoid these exceptions, you must disable the indexing of PDF files.

    Note: Sitecore is currently looking for ways to enable indexing of media items in the Azure App Service environment. The public reference number for this issue is 149879.
