• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty nang x hoi. hieu va cham ((xuc ban) OR (cuc ban)) anh ((hai cua) or (dai cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty nang x hoi. hieu va cham ((xuc ban) OR (cuc ban)) anh ((hai cua) OR (dai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty nang x hoi. hieu va cham ((xuc ban) OR (cuc ban)) anh ((hai cua) or (dai cua)) te".
• Adding a wildcard symbol may retrieve word variants: thu sach ty nang x hoi. hieu va cham ((xuc ban) OR (cuc ban)) anh ((hai cua) or (dai cua)) te*.
