• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty ((nang xa) or (lang van)) hoi. hieu van cam duc van ((thang loi) OR (thanh moi)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((nang xa) OR (lang van)) hoi. hieu van cam duc van ((thang loi) OR (thanh moi)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((nang xa) or (lang van)) hoi. hieu van cam duc van ((thang loi) OR (thanh moi)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((nang xa) or (lang van)) hoi. hieu van cam duc van ((thang loi) OR (thanh moi)) cuu tre*.
