• Performing a fuzzy search may retrieve terms with similar spellings: thu sach y mang xa hoi. hieu va ((cac xuc) or (cac nuoc)) ((van anh) OR (van thanh)) vi dau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y mang xa hoi. hieu va ((cac xuc) OR (cac nuoc)) ((van anh) OR (van thanh)) vi dau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y mang xa hoi. hieu va ((cac xuc) or (cac nuoc)) ((van anh) OR (van thanh)) vi dau tren".
• Adding a wildcard symbol may retrieve word variants: thu sach y mang xa hoi. hieu va ((cac xuc) or (cac nuoc)) ((van anh) OR (van thanh)) vi dau tren*.
