Riak search queries via the java client

Hi Oved. If Riak search is anything like Lucene search, the correct way to
query that would be:

Name:c1 OR Name:c2

Did you try that?  I believe this also works in lucene: Name:(c1 OR c2)

Sorry to answer without actually trying this on Riak, just from my Lucene
experience.  But it's worth a try. Any attribute without a prefix is
interpreted as that value in the default search field.
