Full text index structure (B tree?)

Hi,
I have read about full text index structure being a B-tree with 2 levels. I intend to know the exact structure of this. Here are a few questions I want to address.

1) since its for full text search there needs to be a keyword - inverted list link. How is it handled in mysql indexing? Is it like for a keyword (assuming keyword forms a node in B-tree) with multiple occurrences, we have a single node and its child is a list of docids in which it occurs?

Could anyone please give more information about this and the exact B-tree structure?

Thanks
