[TYPO3] Search index: PDF not indexed

[Patrick]

Hi, the Indexed Search on my site cannot index PDF file (HTML, TXT file 
was indexed). My provider tell me that PDFtoText and PDFinfo was 
installing on the server in /usr/bin folder. My Indexed Search 
configuration was ok (I change the path of pdftools).

I cannot check in shell if the pdftools is working (is a shared hosting, 
i not have a shell access). Is it possible to check the pdftools 
(Pdftotext, pdfinfo) is working in PHP ? I seen in the configuration of 
the plug in a debug mode but where I can see the information of this 
debug mode ?

Thank you for your help.
