But Google has already done a lot toward solving this.

Searching for
  site:research.att.com/~njas ways factor
comes up with A001055 on the second page.

If you compute a few consecutive "interesting" terms, then you can search for
  site:research.att.com/~njas ways factor "4 11 2"
and get your sequence first.  (Oddly, searching with things like 1 2 1
in there seems to make matters worse instead of better.)

Google knows that factor/factors/factorize/etc should all be given
some weight when you search for factor.

In fact I do a lot of my OEIS searches using Google if I'm not happy
with what I find from the search on the main OEIS page.
