Filtering on file metada or attributes

["Claude Mench" <c mench adilinstruments com>]

Hello All,

    I tried out Beagle on Ubuntu, worked ok for me. 
But after looking at all source of infos like the 
wiki, the flash demos, etc... I didn't see a way 
to perform query on the file attributes themselves

    For instance can we search all files modified 
after a given date, or search all files with a 
specified content and who is smaller or bigger 
that a given file size.

    If it's possible could please some give me 
an example of such a query.

    Thanks
