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