• Performing a fuzzy search may retrieve terms with similar spellings: karachi : (emma OR ((spmma OR sama) OR (((suma OR uma) OR sma) OR ((suman OR susan) OR saman))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: karachi : (emma OR ((spmma OR sama) OR (((suma OR uma) OR sma) OR ((suman OR susan) OR saman)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "karachi : (emma OR ((spmma OR sama) OR (((suma OR uma) OR sma) OR ((suman OR susan) OR saman))))".
• Adding a wildcard symbol may retrieve word variants: karachi : (emma OR ((spmma OR sama) OR (((suma OR uma) OR sma) OR ((suman OR susan) OR saman))))*.
