• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky ((((sang ma) OR (nang ma))) or (tang ma)) hoa. hieu va cam qua ban hang vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((((sang ma) OR (nang ma))) OR (tang ma)) hoa. hieu va cam qua ban hang vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((((sang ma) OR (nang ma))) or (tang ma)) hoa. hieu va cam qua ban hang vai cua tre*".
