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