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