Text-based file searching/indexing (txt, html, etc.) is enabled by default. If you want to include searching PDF or Word documents then you need to do the following.

Searching in PDFs

 To enable search in PDFs you need to:

  • Install a program called xpdf
  • Ensure Settings points to where you installed it
  • Ensure that PHP has access to your xpdf directory. (Check your open_basedir PHP setting in php.ini)
  • Ensure that PHP can run the system  function.  (Check your disable_functionssafe_mode_exec_dir PHP settings in php.ini)

Install xpdf

Update the setting to point to xpdf

Once you have installed xpdf, you also need to set the correct path it in the Settings.

  • You can find this under Settings menu, Settings -> Admin -> XPDF installation path
  • Make sure that this points to the directory where you installed xpdf. For example: /usr/local/bin/ or c:/wwwroot/xpdf/
  • Set this to 'off' to de-activate this option.
  • When you click "Save", test pdf file will be parsed/indexed and error occurs if it failed. 

Test xpdf from command line

Test to see if xpdf is working by running the following command from the command line:

$ /path_to_xpdf/pdftotext -raw file_read.pdf file_write.txt;

Test  xpdf from command line using PHP and included test file:
