• If you are trying to use Boolean operators, they must be ALL CAPS: karachi : (umma OR ((sama OR ((suman OR sumn) OR susan)) OR ((suma OR summer) OR summarry))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "karachi : (umma OR ((sama OR ((suman OR sumn) OR susan)) OR ((suma OR summer) OR summarry)))".
