awk to include blank space

[kholikt]

I use awk to look for " omniback" keyword in a file
Before the word omniback I have four blank space

just wondering

If I use awk'/^ omniback/ {print $4}'
I won't get the result correctly

how could I put four black space together with omniback as search pattern in the above command

[kholikt]

just to clarify it is a tab not space

Both these ahould work:
awk'/^\tomniback/ {print $4}'
or
awk'/^omniback/ {print $4}'
