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