Vocabulary with Terms with Multiple Words where each Word is also a Term, how to differentiate

Thanks for the great, useful module.

I have a question trying to figure out:

Assume there are 3 Terms:

John Home
John
Home

The node body contains "John" and "Home", in separate places, such as in a sentence "John today goes home"

In this case, "John" and "Home" terms are assigned to the node, however, "John Home" term is not assigned.

How can I solve this problem ?

The problem with "John Home" not assigned is that,"Home" term refers to many other nodes that "John Home" does not refer ... and the vocabulary needs to have all these terms "John" "Home" "John Home"

Thanks
