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_functions, safe_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 -> Files -> 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;
Searching in Word files
To enable search in Word documents you need to:
- Install a program called catdoc
- Ensure Settings points to where you installed it
- Ensure that PHP has access to your catdoc directory. Check your open_basedir PHP setting in php.ini.
- Ensure that PHP can run the system" function. Check your disable_functions, safe_mode_exec_dir PHP settings in php.ini.
Install catdoc
Update the setting to point to catdoc
Once you have installed catdoc, you also need to set the correct path it in the Settings.
- You can find this under Settings menu, Settings -> Files -> catdoc installation path
- Make sure that this points to the directory where you installed catdoc. For example: /usr/local/bin/ or c:/wwwroot//catdoc
- When you click "Save", test pdf file will be parsed/indexed and error occurs if it failed.
Turning PDF or Word search off
If you don't want to allow searching on PDF or Word documents, change the setting in XPDF installation path or catdoc installation path to OFF.
