Re: [Tracker] Metadata search Tracker Gnome

[John Bestevaar <Josephus people net au>]

OK, so i tried   mlo:city "Beaudesert" in the query box of the Tracker Gui.
No result. :-!
Therefore can i assume that Tracker Gui searches Metadata in images 
using a completely different method from Filename searches and Document 
Content Text searches? Alternatively, is it the case that image metadata 
is encoded in a way that it is not available to Tracker Gui text search? 
:-)
What do you mean by " fts property" ? O:-)
Cheers JohnB
