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