• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ty nang x hoi. hieu va ((cham xuc) OR (cam xuc)) ((va danh) or (gia thanh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty nang x hoi. hieu va ((cham xuc) OR (cam xuc)) ((va danh) OR (gia thanh)) vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty nang x hoi. hieu va ((cham xuc) OR (cam xuc)) ((va danh) or (gia thanh)) vi cua tre".
• Adding a wildcard symbol may retrieve word variants: vu sach ty nang x hoi. hieu va ((cham xuc) OR (cam xuc)) ((va danh) or (gia thanh)) vi cua tre*.
