• Performing a fuzzy search may retrieve terms with similar spellings: so ((sach ky) OR (sac ky)) dang xay hoi. hieu ((van cam) or (van lam)) xuc ban lanh dao cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach ky) OR (sac ky)) dang xay hoi. hieu ((van cam) OR (van lam)) xuc ban lanh dao cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach ky) OR (sac ky)) dang xay hoi. hieu ((van cam) or (van lam)) xuc ban lanh dao cua tre*".
