After restarting beagled (and waiting a bit), there's now results with 
source:Files as well.

When I disable the Locate backend, beagle-query exits after ~19s; 
otherwise it takes ages, even when I use source:Files.

But (slightly OT) I'm wondering why the following query

$ /usr/bin/time beagle-query source:Files filename:reconnaissance 
--verbose

gives this debugging output

Debug: Parsed query 'source:Files' as prop query:key=beagle:Source, 
value=Files and property type=Keyword
Debug: Parsed query 'filename:reconnaissance' as OR of 2 queries:
Debug:  :key=beagle:NoPunctFilename, value=reconnaissance and property 
type=Text
Debug:  :key=beagle:SplitFilename, value=reconnaissance and property 
type=Text
Error: LocateDriver can only search for text and does not support 'OR', 
'NOT' queries.

I thought that the operator "AND" would be used implicitly - and not OR 
as mentioned in the quotation (in the wiki it says "To indicate that 
the word A or word B be in results, use OR"). But perhaps only the 
debugging output is wrong on this one.
Furthermore I don't understand the error from the LocateDriver, since I 
explicitly searched in the "Files" backend. There are no results from 
"Locate", but I'm wondering whether the other backends are searched as 
well, but only filtered from the result list?

Oh, and I'm subscribed to dashboard-hackers, so I receive answers to 
the list :)

Thanks and greetings,

Jens
