• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach 2 lang xa hoi. ((hieu va) or (lieu va)) cam xuc va ((hanh dai) OR (hanh tai)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach 2 lang xa hoi. ((hieu va) OR (lieu va)) cam xuc va ((hanh dai) OR (hanh tai)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach 2 lang xa hoi. ((hieu va) or (lieu va)) cam xuc va ((hanh dai) OR (hanh tai)) cua triet".
• Adding a wildcard symbol may retrieve word variants: thuoc sach 2 lang xa hoi. ((hieu va) or (lieu va)) cam xuc va ((hanh dai) OR (hanh tai)) cua triet*.
