• If you are trying to use Boolean operators, they must be ALL CAPS: toc thieu xanh - ((hanh truong) OR (anh trong)) cua thong ((song anh) OR (song xanh)) tuan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc thieu xanh - ((hanh truong) or (anh trong)) cua thong ((song anh) OR (song xanh)) tuan ban~".
• Adding a wildcard symbol may retrieve word variants: toc thieu xanh - ((hanh truong) or (anh trong)) cua thong ((song anh) OR (song xanh)) tuan ban*.
