Programs installed on server

Hello, I asked hosting company to check the programs installed on server and their paths according to config.inc.php in order to make sure that all search capabilities will work.
I got the following message from the hosting company:
pstotext is not available on our Shared Accounts.
/usr/bin/pdftotext is available and the correct path is used.
/usr/bin/ps2ascii is available and the correct path is used.
antiword is not available on our Shared Accounts.
catdoc is not available on our Shared Accounts.
As far as I see there is no pstotext. Please inform me does missing antiword, catdoc and pstotext prevent us from full text search. We have PDF files only in our OJS installation. We use the latest OJS.

Thanks

In config.inc.php, you will want to choose one application for PDF, one application for postscript, and one application for Microsoft Word, if possible and if relevant.

It sounds like your hosting provider is missing an option for Microsoft Word, but provides options for PDF and for postscript. This will not be a problem if you are only indexing PDF documents.

Be sure to uncomment the pdftotext line in your PDF section of config.inc.php. Leave the pstotext line commented.
