• Performing a fuzzy search may retrieve terms with similar spellings: tu sach tu ((lang xa) OR (lang van)) hoi. lieu va ((nam duc) or (nam duoc)) van thanh lap cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tu ((lang xa) OR (lang van)) hoi. lieu va ((nam duc) OR (nam duoc)) van thanh lap cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tu ((lang xa) OR (lang van)) hoi. lieu va ((nam duc) or (nam duoc)) van thanh lap cau tren".
• Adding a wildcard symbol may retrieve word variants: tu sach tu ((lang xa) OR (lang van)) hoi. lieu va ((nam duc) or (nam duoc)) van thanh lap cau tren*.
