What API can update the data in `doc` dynamically?

[liangyd1024]

For example, what API does business data update through?

Use engine.Index() directly, see the godoc.

Initialize the data of the three indexes here

Here I have updated the data in the index 2

But why does the data in index 2 have two content, why is it not covered?
