Dear all,

I just started learning how to use YQL and met a problem.

In the following webpage, it said

"Local and remote filter expressions can be combined with the boolean AND and OR operators. The AND operator has precedence over the OR operator. To change precedence, enclose expressions in parentheses. "

from http://developer.yahoo.com/yql/guide/filters.html#boolean

So I tried this,

select * from answers.getbycategory (10) where category_id=2115500137 and (region="au" or region ="fr")

But the server returned "Bad request"

What is the correct usage?

Thanks a lot!
