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