• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach ky nang xa hoi. hieu van cac ((bo tuan) OR (bo xuan)) anh ((rija cua) or (giau cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ky nang xa hoi. hieu van cac ((bo tuan) OR (bo xuan)) anh ((rija cua) OR (giau cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ky nang xa hoi. hieu van cac ((bo tuan) OR (bo xuan)) anh ((rija cua) or (giau cua)) te".
• Adding a wildcard symbol may retrieve word variants: thuat sach ky nang xa hoi. hieu van cac ((bo tuan) OR (bo xuan)) anh ((rija cua) or (giau cua)) te*.
