• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang ma hoi. hieu ve ((cham luc) OR (cham soc)) va hanh ((le cuu) OR (le huu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ma hoi. hieu ve ((cham luc) or (cham soc)) va hanh ((le cuu) OR (le huu)) tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang ma hoi. hieu ve ((cham luc) or (cham soc)) va hanh ((le cuu) OR (le huu)) tre*.
