• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach van) OR (bach van)) nang xa hoi. ((hieu van) or (thien van)) cau phuc van hanh le cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach van) OR (bach van)) nang xa hoi. ((hieu van) OR (thien van)) cau phuc van hanh le cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach van) OR (bach van)) nang xa hoi. ((hieu van) or (thien van)) cau phuc van hanh le cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach van) OR (bach van)) nang xa hoi. ((hieu van) or (thien van)) cau phuc van hanh le cua tre*.
