• Performing a fuzzy search may retrieve terms with similar spellings: (((( tu cach ((kinh de) OR (kinh te)) giau tuong ) or ( tu cach kinh hoc gia tuong ))) or ((( tu cac tinh doi gia luong ) or ( tu cac trinh dong giam muong ))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((( tu cach ((kinh de) OR (kinh te)) giau tuong ) OR ( tu cach kinh hoc gia tuong ))) OR ((( tu cac tinh doi gia luong ) OR ( tu cac trinh dong giam muong )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( tu cach ((kinh de) OR (kinh te)) giau tuong ) or ( tu cach kinh hoc gia tuong ))) or ((( tu cac tinh doi gia luong ) or ( tu cac trinh dong giam muong ))))".
• Adding a wildcard symbol may retrieve word variants: (((( tu cach ((kinh de) OR (kinh te)) giau tuong ) or ( tu cach kinh hoc gia tuong ))) or ((( tu cac tinh doi gia luong ) or ( tu cac trinh dong giam muong ))))*.
