• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) or (vu bach)) thu sang ma hoi. lieu va dau ((truc van) OR (truc ban)) hanh di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu bach)) thu sang ma hoi. lieu va dau ((truc van) OR (truc ban)) hanh di cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (vu bach)) thu sang ma hoi. lieu va dau ((truc van) OR (truc ban)) hanh di cuu tre*".
