Thinking Sphinx

Search criteria
1.Searching with the combination of the “AND” and “OR” conditions for
four to five fields of the table.
-Added the indexes for the search fields.
Ex1. Order.search(:conditions=>[“store_id=16 and
(store_order_id=‘23432’ or store_customer_id=‘23432’)” ])
-This query is returning the empty result set.

Ex2.
Order.search(:conditions=>{:store_id=>16,:store_order_id=>“23432”,:store_customer_id=>“23432”})
-This query works perfectly,but this is a combination of the “AND”
condition.

Trying to find a solution to search on the multiple fields combined with
“AND” and “OR” conditions.
