If you run OCR you should get a document that contains recognized characters and words that can then be searched.
The 2011 LFBC PDF when opened in Adobe Illustrator contains no searchable text, and there are no recognized fonts.
What you do get when you open the file is 9 or 10 layers that build up logically, perfectly separating out elements of the document such as:
1/ The Registrars stamp
2/ The date stamp
3/ The green security paper pattern
4/ The signatures
That's the short version, if you want the full version watch the cold case pose press conference:-

Its 1hr 20mins of high quality video professionally presented. If you have slow broadband it won't be fun trying to view it.
Thanks
