• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thi hang xa hoi. hieu ((ve cam) or (va cam)) xuc ((va thanh) OR (ban thanh)) vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thi hang xa hoi. hieu ((ve cam) OR (va cam)) xuc ((va thanh) OR (ban thanh)) vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thi hang xa hoi. hieu ((ve cam) or (va cam)) xuc ((va thanh) OR (ban thanh)) vai cua triet".
