• Performing a fuzzy search may retrieve terms with similar spellings: (((("tu sach kinh ho gia cong") or ("thuoc sach kinh o gian muong"))) or ((("su sach kinh o gia tuong") or ((("so sach kinh o gia tuong") OR ("so sach kinh o va tuong"))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("tu sach kinh ho gia cong") OR ("thuoc sach kinh o gian muong"))) OR ((("su sach kinh o gia tuong") OR ((("so sach kinh o gia tuong") OR ("so sach kinh o va tuong")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"tu sach kinh ho gia cong\") or (\"thuoc sach kinh o gian muong\"))) or (((\"su sach kinh o gia tuong\") or (((\"so sach kinh o gia tuong\") OR (\"so sach kinh o va tuong\"))))))".
• Removing quotes may allow a broader search: (((( tu sach kinh ho gia cong ) or ( thuoc sach kinh o gian muong ))) or ((( su sach kinh o gia tuong ) or ((( so sach kinh o gia tuong ) OR ( so sach kinh o va tuong )))))).
• Adding a wildcard symbol may retrieve word variants: (((("tu sach kinh ho gia cong") or ("thuoc sach kinh o gian muong"))) or ((("su sach kinh o gia tuong") or ((("so sach kinh o gia tuong") OR ("so sach kinh o va tuong"))))))*.
