• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ly nang x hoi. lieu ((va tham) OR (va cham)) ((goc va) or (loc va)) hanh te cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ly nang x hoi. lieu ((va tham) OR (va cham)) ((goc va) OR (loc va)) hanh te cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ly nang x hoi. lieu ((va tham) OR (va cham)) ((goc va) or (loc va)) hanh te cua triet".
• Adding a wildcard symbol may retrieve word variants: thu sach ly nang x hoi. lieu ((va tham) OR (va cham)) ((goc va) or (loc va)) hanh te cua triet*.
