Indeed lowercasing all the queries make them work.

Sorry my mistake. The queries I did were with:

  "<rubyonrails-talk@googlegroups.com>"

in this case the result is zero but if I remove the "<" and ">" then I get the 
expected results. The same goes for "[rails]" that does not work unless I 
remove the square brackets.

You are rigth, the last query works correclty. Maybe I was already tired of so 
much testing and forgot to actually run the query after setting it.

Once the UTF-7 encoding issue with the labels get's fixed I will test querying 
with Japanese labels.
