• Performing a fuzzy search may retrieve terms with similar spellings: (((((("tu cach kinh he gia tuong") OR ("tu cac tinh he gia tuong"))) or ("tu cach kinh do gia cuong"))) or ("tu sac tinh doi gian muong"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("tu cach kinh he gia tuong") OR ("tu cac tinh he gia tuong"))) OR ("tu cach kinh do gia cuong"))) OR ("tu sac tinh doi gian muong")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"tu cach kinh he gia tuong\") OR (\"tu cac tinh he gia tuong\"))) or (\"tu cach kinh do gia cuong\"))) or (\"tu sac tinh doi gian muong\"))".
• Removing quotes may allow a broader search: (((((( tu cach kinh he gia tuong ) OR ( tu cac tinh he gia tuong ))) or ( tu cach kinh do gia cuong ))) or ( tu sac tinh doi gian muong )).
• Adding a wildcard symbol may retrieve word variants: (((((("tu cach kinh he gia tuong") OR ("tu cac tinh he gia tuong"))) or ("tu cach kinh do gia cuong"))) or ("tu sac tinh doi gian muong"))*.
