• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky ((sang mai) or (sang tai)) hoi. hieu ((ve cam) OR (ve cac)) xuc va lang tai cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky ((sang mai) OR (sang tai)) hoi. hieu ((ve cam) OR (ve cac)) xuc va lang tai cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky ((sang mai) or (sang tai)) hoi. hieu ((ve cam) OR (ve cac)) xuc va lang tai cau tren".
• Adding a wildcard symbol may retrieve word variants: tu cac ky ((sang mai) or (sang tai)) hoi. hieu ((ve cam) OR (ve cac)) xuc va lang tai cau tren*.
