• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty ((hang xa) or (hang ca)) hoi. hieu ve cham ((tuc ban) OR (thuc ban)) thanh ly cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((hang xa) OR (hang ca)) hoi. hieu ve cham ((tuc ban) OR (thuc ban)) thanh ly cua vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((hang xa) or (hang ca)) hoi. hieu ve cham ((tuc ban) OR (thuc ban)) thanh ly cua vat".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((hang xa) or (hang ca)) hoi. hieu ve cham ((tuc ban) OR (thuc ban)) thanh ly cua vat*.
