• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty ((nang x) or (tang ma)) hoi. hieu qua cam ((xuc ban) OR (duc ban)) banh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty ((nang x) OR (tang ma)) hoi. hieu qua cam ((xuc ban) OR (duc ban)) banh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty ((nang x) or (tang ma)) hoi. hieu qua cam ((xuc ban) OR (duc ban)) banh di cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ty ((nang x) or (tang ma)) hoi. hieu qua cam ((xuc ban) OR (duc ban)) banh di cua tre*.
