• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang lap hai. hieu ((ve cam) OR (va cam)) xuc va ((dan va) or (dan ca)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang lap hai. hieu ((ve cam) OR (va cam)) xuc va ((dan va) OR (dan ca)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang lap hai. hieu ((ve cam) OR (va cam)) xuc va ((dan va) or (dan ca)) cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang lap hai. hieu ((ve cam) OR (va cam)) xuc va ((dan va) or (dan ca)) cua te*.
