• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sac ky) OR (sai ky)) nang ma hoi. hieu ve cac xuc va thanh ((va chu) or (ca chua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sac ky) OR (sai ky)) nang ma hoi. hieu ve cac xuc va thanh ((va chu) OR (ca chua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sac ky) OR (sai ky)) nang ma hoi. hieu ve cac xuc va thanh ((va chu) or (ca chua)) tre".
• Adding a wildcard symbol may retrieve word variants: thu ((sac ky) OR (sai ky)) nang ma hoi. hieu ve cac xuc va thanh ((va chu) or (ca chua)) tre*.
