mongoengine query projection

Question

I want projection in mongoengine raw query , here is my query but it don't works

query  =  {'$or':[{'col1':{'$regex':srch_text}},{'col2':{'$regex':srch_text}},{'col3':{'$regex':srch_text}}]}

projection = {'col4':0}
test= Test.objects(__raw__=(query,projection))

p.s : without projection it works

test= Test.objects(__raw__=(query))

Answer 1

__raw__ doesn't take a projection, so you should combine with only eg:

tests = Test.objects(__raw__=(query)).only('col4')
