I need to search for text in a bulk of pdf files.
These files are "normal" PDF files and others are generated with Adobe Livecycle and are "PDF 1.7" files.
On the normal files I can search text using for example PDF-XChange Viewer (rif. http://www.tracker-software.com/product/pdf-xchange-viewer) or Recoll (rif. http://www.lesbonscomptes.com/recoll/) but they don't work on "PDF 1.7" files.
Are there some solutions that work on both types of PDF files?
Any suggestions? Thank you very much in advance
