phpStorm, do not index a folder / tree

Question

I can't find the ability of phpStorm 5 to avoid indexing a specific folder. I don't want to exclude it from the Project-View, just don't want phpStorm to index the containing folders, classes, functions etc.

How is that possible?

Solution

From their documentation, looks like the only way to achieve this is to Exclude the directory which will hide it from the project tree...

PhpStorm Documentation

To have PhpStorm ignore the selected directory during indexing, parsing, code completion, etc., click the Excluded toolbar button or choose Excluded on the context menu of the selection.
