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