[Pw_forum] one question on |psi|^2

[lfhuang]

Dear PWSCF developers:
     I have a question on |psi|^2 when using projwfc.x and reading projwfc.f90:
 Does |psi|^2 just denote the "Lowdin charge/net atomic charges" for specific band at specific k point? And the "bonding charges" are not included, are'nt they? 
I guess so, because there is: 
proj(nwfc,ibnd,ik)=ABS(proj0(nwfc,ibnd))**2
in projwfc.f90, am I right?
Maybe the questions on the calculations of Lowdin charge and PDOS have been proposed so many times, but my question is somewhat specific and any reply can help my understanding of the code. 
I would like to highly appreciate any helpful comment!

PS: I cannot open the "TOOLs/search facility" on the homepage of PWSCF in China, because if I click it, the page will jump to "Google". Is this normal? It is not like this before. Is the "search facility" related with Google?
In addition, Google company has retreated out of the Inland of China to Hongkong recently, and does this will affect our usage of "search facility"? 

Best Wishes!
Yours Sincerely
L.F.Huang
