How do I ignore a folder, such as node_module?

Is it possible to ignore folders for ctrlSF configuration like ctrlP configuration ignoreDir?

How do I specify to search for a folder (path)?
Look at the ctrlSF help document, which is an example of the following one.
Search in a specific sub-directory

:CtrlSF {pattern} /path/to/dir

However, I do not know whether path is written relative to the directory (d:/workspace/project) where gvim is currently running (/src/views/), or according to the full address (D:/workspace/project/src/views/)
