Alonso Del Arte makes a very important point!
Here is an example from my own experience. I neglected to start my entry in the search box with a(2) and searched for 1, 2, 6, 42, 1806. Thus failed to find A054377 until late in the process of writing a paper on the sequence prefixed by "1". That caused a much bigger change in the paper than if I had found A054377 early on.

Another common situation is when a(1) differs but all the other terms
are the same, due to different approaches in handling 1's unique
qualities. Some people know enough to start their entry in the search
box with a(2) or even a(3), but there will certainly be others who put
start with a(1) and it would certainly benefit them to get a result
with a cross-reference to the sequence with the different a(1).
