• If you are trying to use Boolean operators, they must be ALL CAPS: ho cua sinh - hanh ((thong cua) OR (tang cua)) hang cong ((san cho) OR (sang cho)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho cua sinh - hanh ((thong cua) or (tang cua)) hang cong ((san cho) OR (sang cho)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho cua sinh - hanh ((thong cua) or (tang cua)) hang cong ((san cho) OR (sang cho)) cau*.
