• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty ((hang xa) OR (hang va)) hoi. hieu ve cham tuc va ((tinh thai) or (tinh toan)) cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((hang xa) OR (hang va)) hoi. hieu ve cham tuc va ((tinh thai) OR (tinh toan)) cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((hang xa) OR (hang va)) hoi. hieu ve cham tuc va ((tinh thai) or (tinh toan)) cau treo".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((hang xa) OR (hang va)) hoi. hieu ve cham tuc va ((tinh thai) or (tinh toan)) cau treo*.
