• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ty) or (sach tu)) hang xa hoi. hieu va cuoc luc ((van hanh) OR (ban hanh)) vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach tu)) hang xa hoi. hieu va cuoc luc ((van hanh) OR (ban hanh)) vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) or (sach tu)) hang xa hoi. hieu va cuoc luc ((van hanh) OR (ban hanh)) vai cua te".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ty) or (sach tu)) hang xa hoi. hieu va cuoc luc ((van hanh) OR (ban hanh)) vai cua te*.
