We are currently using Adobe iFilter on our servers to index PDFs however certain PDFs are not being indexed. The content of the PDFs in question is text (not images). Are there any documented limitations for searching types of PDF file formats/versions (i.e. fillable PDFs, Adobe standard vs. Adobe Pro etc.). We are able to index PDFs when we install Foxit PDF iFilter product. We don't want to go down that route as their is a significant cost impact for our server environments. Would really like some support from Adobe on this one or the community. Tried to get in touch with support but they do not support the product which is frustrating. Why develop a product if you're not going to support it!
