As an update to this, I can add and search .doc, .docx and .pdf files - I reinstalled the latest version of smalot's pdfparser as I was receiving some font issues.
HOWEVER, for some reason the set up does not like every type of PDF file. I've not yet investigated any further, but in trying to keep posts complete, I receive the following warning:-
Warning: array_map(): Argument #2 should be an array in /home/public_html/recruiter/lib/DocumentToText.php on line 252
Warning: implode(): Invalid arguments passed in /home/public_html/recruiter/lib/DocumentToText.php on line 253
Starting at line 249:-
Code: Select all/* Store the raw output for getRawOutput(). */
$commandResult['output'] = array_map(
'rtrim', $commandResult['output']
);
$this->_rawOutput = implode("\n", $commandResult['output']);
