• If you are trying to use Boolean operators, they must be ALL CAPS: toc thieu xanh - ((hanh bang) OR (anh bang)) cua nung phong ((va toan) OR (bai toan)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc thieu xanh - ((hanh bang) or (anh bang)) cua nung phong ((va toan) OR (bai toan)) tap~".
• Adding a wildcard symbol may retrieve word variants: toc thieu xanh - ((hanh bang) or (anh bang)) cua nung phong ((va toan) OR (bai toan)) tap*.
