filter query parsing problem

[John Thorhauer]

I am submitting a query and it seems to be parsing incorrectly.  Here
is the query with the debug output.  Any ideas what the problem is:

<arr name="filter_queries">
  <str>
    ((VLog:814124 || VLog:12342) && (PublisherType:U || PublisherType:A))
  </str>
</arr>
<arr name="parsed_filter_queries">
    <str>+(VLog:814124 VLog:12342) +PublisherType:u</str>
</arr>

I would have thought that the parsed filter would have looked like this:
        <str>+(VLog:814124 VLog:12342) +(PublisherType:u PublisherType:a)</str>

Thanks for the help,
