• Performing a fuzzy search may retrieve terms with similar spellings: thuat ((sach hay) or (sach thu)) ((hang xa) OR (hang va)) hoi. hieu ve cac xuc va hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((sach hay) OR (sach thu)) ((hang xa) OR (hang va)) hoi. hieu ve cac xuc va hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((sach hay) or (sach thu)) ((hang xa) OR (hang va)) hoi. hieu ve cac xuc va hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: thuat ((sach hay) or (sach thu)) ((hang xa) OR (hang va)) hoi. hieu ve cac xuc va hanh vi cua te*.
