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