Does PDFNet support Adobe’s Indexing?
If you are asking about the Adobe Catalog Index (pdx file format), this is a proprietary Adobe format, and we are not aware of any other applications supporting it. It is not part of the PDF standard. If your objective is indexing, then you would probably get better results using something like Lucene (and using a PDF library, like PDFNet, to extract the text from the PDF files). To extract text using PDFNet see the following sample code.
