• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cach) or (thu sach)) y nang xa hoi. lieu va luat tuc va ((hanh di) OR (hang di)) cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (thu sach)) y nang xa hoi. lieu va luat tuc va ((hanh di) OR (hang di)) cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (thu sach)) y nang xa hoi. lieu va luat tuc va ((hanh di) OR (hang di)) cua tu".
• Adding a wildcard symbol may retrieve word variants: ((tu cach) or (thu sach)) y nang xa hoi. lieu va luat tuc va ((hanh di) OR (hang di)) cua tu*.
