• If you are trying to use Boolean operators, they must be ALL CAPS: vu bach ty ((hang ca) OR (hang tai)) hoi. lieu va cam duc van thanh va ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu bach ty ((hang ca) OR (hang tai)) hoi. lieu va cam duc van thanh va ((cua te) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: vu bach ty ((hang ca) OR (hang tai)) hoi. lieu va cam duc van thanh va ((cua te) or (cua tu))*.
