Customizing the title for PDF documents in Sitecore
I know that Coveo uses a Title Selection Sequence to try to determine the title of PDF documents. For some of our PDF documents the file name is used for the title. I want to change this to something more meaningful. First I tried setting the "Title" of the PDF item (the Data Template for PDFs in Sitecore has a Title field). I also tried creating a Post Item Processor to set the "args.CoveoItem.Title". Neither of these approaches worked.
From what I can tell, if I was to change the Title Selection Sequence as specified here, I may be able to get this to work. The problem is, I can't find where to set the title selection sequence. I am using the "SitecoreCloudTrialEdition" and am on version 4.0.450. From what I have heard, this version does not support changing the Title Selection Sequence.
I know I can create an alternate field to store a "title", but we would like the benefit of setting the official title so it will have a higher weighting.
Is there a way to override the Title for PDF documents?
