• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sach ty) OR (sach tu)) ((lang van) or (tang van)) hoi. hieu van cam xuc va hanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach ty) OR (sach tu)) ((lang van) OR (tang van)) hoi. hieu van cam xuc va hanh vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach ty) OR (sach tu)) ((lang van) or (tang van)) hoi. hieu van cam xuc va hanh vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: vu ((sach ty) OR (sach tu)) ((lang van) or (tang van)) hoi. hieu van cam xuc va hanh vi cuu tre*.
