Problems with placefinder YQL query - using neighborhood OR city

Hi all,

I can't seem to get this YQL to work as expedcted with the placefinder API:

SELECT * FROM geo.placefinder
WHERE (neighborhood="clifton" OR city="clifton")
AND locale="GB" AND gflags="L"

I get zero results when there definitely should be some. This for example does produce results:

SELECT * FROM geo.placefinder
WHERE neighborhood="clifton" 
AND locale="GB" AND gflags="L"

It doesn't seem to like the OR clause in the parentheses at all.

Thanks in advance,

Alex
