Yep, but I'm not really sure the query, foo bar, really is invalid.
According to the Gentle Introduction to CQL:

   In general, multi-word terms are interpreted as requesting
   records in which a single field contains all the specified
   words, in the specified order, with no other words in
   between. This is a proximity search. But see the section
   below on relations for exceptions.

I posted a (long) message to the list for verification.
