trach nhiem » trac nghiem
nghiem dau » nghiep dau, nghiem va, nghiem ban
dat trach » sat trach, dat thanh, dat khach
anh tinh » canh tinh, hanh tinh, manh tinh
dau hoc » dai hoc, du hoc, dan hoc
huu loc » hau loc, muu luoc
tu anh » tu hanh, tu manh, thu anh

• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu anh tinh nghiem dau hoc ) OR ( tu dat trach nhiem huu loc ))*.
