• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty sang ma hoi. hieu ((van dau) OR (van dao)) xuc van ((hanh tai) or (hanh va)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty sang ma hoi. hieu ((van dau) OR (van dao)) xuc van ((hanh tai) OR (hanh va)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty sang ma hoi. hieu ((van dau) OR (van dao)) xuc van ((hanh tai) or (hanh va)) cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ty sang ma hoi. hieu ((van dau) OR (van dao)) xuc van ((hanh tai) or (hanh va)) cua te*.
