• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty ((((xang xa) OR (lang xa))) or (mang xa)) hoi. hieu va cam xuc va thanh ha cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((((xang xa) OR (lang xa))) OR (mang xa)) hoi. hieu va cam xuc va thanh ha cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((((xang xa) OR (lang xa))) or (mang xa)) hoi. hieu va cam xuc va thanh ha cua viet".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((((xang xa) OR (lang xa))) or (mang xa)) hoi. hieu va cam xuc va thanh ha cua viet*.
