• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky dang ma hoi. hieu ((vu cam) or (vu cham)) ly va ((thanh hai) OR (thanh phan)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky dang ma hoi. hieu ((vu cam) OR (vu cham)) ly va ((thanh hai) OR (thanh phan)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky dang ma hoi. hieu ((vu cam) or (vu cham)) ly va ((thanh hai) OR (thanh phan)) cua triet".
• Adding a wildcard symbol may retrieve word variants: thu sach ky dang ma hoi. hieu ((vu cam) or (vu cham)) ly va ((thanh hai) OR (thanh phan)) cua triet*.
