"Parsing" and "scannings" indicators not explained

The problem is discovered on Qt Creator 2.0.94.

"Parsing" and "scannings" indicators: no help article found for the indicators when searching for this words in the Help.
Neither they are explained in the Help article "Qt Creator User Interface".
IMHO (no previous experience with Qt Creator), these different indicators do not add any value.
If the code / project cannot be edited / compiled right after opening, one indicator would be sufficient.
