• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky dang xa hoi. lieu va nam xuc va ((thanh va) OR (thanh van)) ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky dang xa hoi. lieu va nam xuc va ((thanh va) OR (thanh van)) ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky dang xa hoi. lieu va nam xuc va ((thanh va) OR (thanh van)) ((cua tre) or (cua triet))".
