• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ky) or (sac ky)) nang cong hai. hieu va cam xuc ((ban anh) OR (ban danh)) di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) nang cong hai. hieu va cam xuc ((ban anh) OR (ban danh)) di cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sac ky)) nang cong hai. hieu va cam xuc ((ban anh) OR (ban danh)) di cua triet".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (sac ky)) nang cong hai. hieu va cam xuc ((ban anh) OR (ban danh)) di cua triet*.
