A peaceful night for you,
I noticed for some quadratic polynomial, such as f(n)=n²+1, f(n)=2n²-1, f(n)=2n²+1 and f(n)=4n²+1 you can make a linear substitution with n=p*k+n0 with p|f(n) and...

a prime sieve for f(n)=n⁴+1
A peaceful night,
the sieve algorithm for the function f(n)=2n²-1 was too slow,
even with some improvements.
The function f(n)=n^p-1 increase too fast for practical use.
