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