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