• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty nang x hoi. hieu ((ve cham) or (ve chat)) ((truc va) OR (thuc va)) dan lap cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang x hoi. hieu ((ve cham) OR (ve chat)) ((truc va) OR (thuc va)) dan lap cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang x hoi. hieu ((ve cham) or (ve chat)) ((truc va) OR (thuc va)) dan lap cau tren".
• Adding a wildcard symbol may retrieve word variants: su sach ty nang x hoi. hieu ((ve cham) or (ve chat)) ((truc va) OR (thuc va)) dan lap cau tren*.
