• Performing a fuzzy search may retrieve terms with similar spellings: hoc hien xanh - hanh ((((trang cua) OR (trung cua))) or (ban cua)) thong cong dan than ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - hanh ((((trang cua) OR (trung cua))) OR (ban cua)) thong cong dan than ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - hanh ((((trang cua) OR (trung cua))) or (ban cua)) thong cong dan than ban*".
