• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty hang xa hoi. hieu ((ve cam) or (ve cac)) tuc va ((hanh lam) OR (hanh kem)) cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty hang xa hoi. hieu ((ve cam) OR (ve cac)) tuc va ((hanh lam) OR (hanh kem)) cau tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty hang xa hoi. hieu ((ve cam) or (ve cac)) tuc va ((hanh lam) OR (hanh kem)) cau tren*".
