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