• If you are trying to use Boolean operators, they must be ALL CAPS: toc hieu manh - ((hoang ban) OR (hang ban)) cua thang long ((van phan) OR (van phong)) tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc hieu manh - ((hoang ban) OR (hang ban)) cua thang long ((van phan) or (van phong)) tu~".
• Adding a wildcard symbol may retrieve word variants: toc hieu manh - ((hoang ban) OR (hang ban)) cua thang long ((van phan) or (van phong)) tu*.
