aha, then is that the problem. Because var1 has 2.3 million observations and var2 has 5000 observation.
However, the values of var2 are more than once in var1.
I am gonna try this, thank you :)

gen var3 = var1 == var2
is certainly a good way to create a variable saying whether two
variables are the same. But what do you mean that "this is not
working"?
Note that -- necessarily -- this syntax compares values in the same
observation, and not in different observations.
gen var4 = var1 == var2[_n-1]
illustrates an extension which may be closer to what you seek.
