Answer 1

You can use pdfgrep see this link How to search contents of multiple pdf files? I have also used it few times and it also supports recursive search.

As Amal Murali wrote in comment, you have to convert PDF content to text. This has been already solved at StackOverflow, ie How to extract text from the PDF document? . Then you can use preg_match_all, or if you really want to use grep, you can use something as proc_open and pass the text through pipe.

So, using class from http://pastebin.com/hRviHKp1 (link from article), here is an example with preg_match_all:

include('class.pdf2text.php');
$a = new PDF2Text();
$a->setFilename('Videographer_RFP.pdf');
$a->decodePDF();
preg_match_all ('some pattern', $a->output(), $matches);
print_r($matches);

Note that I have not tested the code.
