• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu thang ma hoi. hieu ((van cau) OR (van chat)) ((truc va) or (thuc va)) hanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu thang ma hoi. hieu ((van cau) OR (van chat)) ((truc va) OR (thuc va)) hanh vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu thang ma hoi. hieu ((van cau) OR (van chat)) ((truc va) or (thuc va)) hanh vi cuu tre".
