What's the meaning of lai2 in this sentence? Is it a common meaning of this? What are other examples in which I can use it with this meaning? Is "fang1 shi4 lai2" a fixed expression? What does it mean?

It seems to me that it's [description of method] + fang1 shi4 lai2 + [verb] and it means "to do [verb] in a [description] way".
