• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach y)) ((lang xa) OR (lang ha)) hoi. lieu va cac toc van doanh van cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sach y)) ((lang xa) OR (lang ha)) hoi. lieu va cac toc van doanh van cua te~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (sach y)) ((lang xa) OR (lang ha)) hoi. lieu va cac toc van doanh van cua te*.
