Optimizing search times

Hello,

I'm trying to find all windowsupdate.log files which are located in different user profiles under:
\\SERVERNAME\c$\Users\USERNAME\AppData\Local\Microsoft\Windows\WindowsUpdate.log

what is the best way to search for all these files with an advanced search ?

I tried several things based on what I could find on this forum, like for instance limiting the location to *\*\*\*\*\*
I tried to search for the following Full Path too:
\\SERVERNAME\c$\Users\*\AppData\Local\Microsoft\Windows\WindowsUpdate.log

but it seems that it is parsing all folders and subfolders instead of directly fetching the wanted file.

A quick thought (untested):

Replace * with something more limiting, like [^\\]+ or [\w]+ (needs RegEx on).
