• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty nang xa hoi. hieu va ((((cac lo) OR (cac lop))) OR (cac co)) va hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty nang xa hoi. hieu va ((((cac lo) OR (cac lop))) OR (cac co)) va hanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ty nang xa hoi. hieu va ((((cac lo) OR (cac lop))) OR (cac co)) va hanh vai cua tre*.
