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