[Feature request] Search folders/files and within files

It would great if CKFinder has a search function to search folders and files AND within files (full text search).

Drupal has a search module that searches text within text, Word, Excel, Powerpoint, PDF and RTF files using these free modules (for unix):

pdftotext
catdoc
xls2csv
catppt
unrft
cat
