• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky sang ma hoi. hieu va cam ((xuc vay) or (xuc hay)) ((doanh va) OR (doan va)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky sang ma hoi. hieu va cam ((xuc vay) OR (xuc hay)) ((doanh va) OR (doan va)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky sang ma hoi. hieu va cam ((xuc vay) or (xuc hay)) ((doanh va) OR (doan va)) cua te*".
