Can nox indexes for the whole project? Not a single source file.

Nox is fast , but i find it can't auto complete for the whole project. Now i use it to write some codes in the linux kernel.
Nox can help me complete the membet of a struct variable, but it only support the variable definited in the current source.
When i use a new variable of another src, it can't work! Why?
