Perhaps you should try some spelling variations:
gian muong » giang duong, gian trong
trinh doc » trinh do, trinh hoa, trinh co
gia tuong » gia cuong, gia cong, gia tang
doc gian » don gian, duoc giao, dan gian
hoc giai » hoc giao, hoc dai, so giai
dac tinh » may tinh, ha tinh, ban tinh

doi nam » noi nam, voi nam, dong nam
tu cach » tu cac
kinh co » tinh co, trinh co, kinh hoc
kinh do » trinh do, kinh hoc, tinh doi
tu lap » truc lap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( tu cach ((kinh do) or (kinh co)) gia tuong ) or ((( tu ((sac tinh) OR (dac tinh)) ((hoc giai) or (doi nam)) muong ) or ( tu lap trinh doc gian muong ))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu cach ((kinh do) OR (kinh co)) gia tuong ) OR ((( tu ((sac tinh) OR (dac tinh)) ((hoc giai) OR (doi nam)) muong ) OR ( tu lap trinh doc gian muong )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu cach ((kinh do) or (kinh co)) gia tuong ) or ((( tu ((sac tinh) OR (dac tinh)) ((hoc giai) or (doi nam)) muong ) or ( tu lap trinh doc gian muong ))))".
• Adding a wildcard symbol may retrieve word variants: (( tu cach ((kinh do) or (kinh co)) gia tuong ) or ((( tu ((sac tinh) OR (dac tinh)) ((hoc giai) or (doi nam)) muong ) or ( tu lap trinh doc gian muong ))))*.
