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