• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ly) OR (sach y)) ((nang mai) or (nang ma)) hoi. lieu va cam xuc ban hanh vi cua duc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ly) OR (sach y)) ((nang mai) OR (nang ma)) hoi. lieu va cam xuc ban hanh vi cua duc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ly) OR (sach y)) ((nang mai) or (nang ma)) hoi. lieu va cam xuc ban hanh vi cua duc".
• Adding a wildcard symbol may retrieve word variants: su ((sach ly) OR (sach y)) ((nang mai) or (nang ma)) hoi. lieu va cam xuc ban hanh vi cua duc*.
