The local distribution of the number of small prime factors - variation of the classical theme

We obtain uniform estimates for $N_k(x,y)$, the number of positive integers $n$ up to $x$ for which $\omega_y(n)=k$, where $\omega_y(n)$ is the number of distinct prime factors of $n$ which are $ 0$ by the Buchstab-de Bruijn method. We also utilize a certain recent result of Tenenbaum to complete our asymptotic analysis.
