• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - hanh ((trang cua) OR (tang cua)) nhung song van ((tuan cao) OR (quang cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh ((trang cua) or (tang cua)) nhung song van ((tuan cao) OR (quang cao))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh ((trang cua) or (tang cua)) nhung song van ((tuan cao) OR (quang cao))*.
