• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky ((((dang xa) OR (dang ha))) or (lang xa)) hoi. lieu va cac duc tran thanh hoi cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky ((((dang xa) OR (dang ha))) OR (lang xa)) hoi. lieu va cac duc tran thanh hoi cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky ((((dang xa) OR (dang ha))) or (lang xa)) hoi. lieu va cac duc tran thanh hoi cua viet".
• Adding a wildcard symbol may retrieve word variants: vu sach ky ((((dang xa) OR (dang ha))) or (lang xa)) hoi. lieu va cac duc tran thanh hoi cua viet*.
