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