querying multidimensional sequences in OEIS

I have a sequence indexed by vectors with non-negative integer components.
Is there a regular way to query such sequence in OEIS ?
As an example, let us consider a sequence of multinomial coefficients.
Any vector with non-negative integer components [k1, k2, ..., kn]
defines an element of this sequence:
a( [k1, k2, ..., kn] ) = (k1 + k2 + ... + kn)! / (k1! * k2! * ... * kn!)
Assume that I know nothing about these numbers and have only a
black-box computing a(v) for any given vector v with non-negative
integer components. Can I anyhow find this sequence in OEIS and learn
that its elements called "multinomial coefficients" ?
Thanks,
Max
