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