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