The filesearch module uses some command line programs for file indexing. Make sure the following commands are executable: catdoc xls2csv unzip tar imagemagick pdf2text pdfinfo tesseract-ocr exiv2 Also make sure PHP5 has the php5-xsl extension installed. The search index must be updated in a cron job: /usr/share/groupoffice/groupofficecli.php -c=/etc/groupoffice/config.php -r=filesearch/filesearch/sync This cronjob will run every night when using the debian packages.
