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