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