• Performing a fuzzy search may retrieve terms with similar spellings: karachi : (emma OR (((((summar OR sumar) OR summer) OR lemma) OR (sumary OR sugary)) OR summa))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: karachi : (emma OR (((((summar OR sumar) OR summer) OR lemma) OR (sumary OR sugary)) OR summa)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "karachi : (emma OR (((((summar OR sumar) OR summer) OR lemma) OR (sumary OR sugary)) OR summa))".
