• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((thu hang) or (ly hang)) ca hoi. lieu va cac xuc va dinh dien ((cua viet) OR (hoa viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((thu hang) OR (ly hang)) ca hoi. lieu va cac xuc va dinh dien ((cua viet) OR (hoa viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((thu hang) or (ly hang)) ca hoi. lieu va cac xuc va dinh dien ((cua viet) OR (hoa viet))".
• Adding a wildcard symbol may retrieve word variants: te sach ((thu hang) or (ly hang)) ca hoi. lieu va cac xuc va dinh dien ((cua viet) OR (hoa viet))*.
