I am using Windows 10 Pro (1709).
A few times in last weeks I have noticed that search from start menu wont find any files. Simply rebuilding the index did not fix this. Looking deeper into indexing settings I found that there was strange looking path being included in the index, one that I had not put there.
The included path looks like this:
csc://{S-1-5-21-773843817-2136397924-2028731201-1001}/
Mouse over this path bring up text saying that this path is not available and cannot be indexed.
Start of the path looks like protocol definition but I could find information about any csc
protocol. The second part is SID
of my user account. (I am only user on this computer and it is not connected to domain.)
Removing that path from indexing targets and rebulding the index has fixed this problem so far but I would like know
1) What is this path
2) Why does it get added to search indexing on its own
3) How can I prevent this from happening again and breaking my search

CSC stands for "Client Side Cache" which is used to hold Offline Files. These are local copies of files that exist on SMB shares like mapped network drives. By default, Windows indexes the CSC so that you can quickly find any network files that you've opened recently. The CSC index can become corrupt and put a full bork on indexing.
Solution:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Csc\Parameters
FormatDatabase
and set its value to1
Open Manage Offline Files
Disable Offline Files
Open Indexing Options
Click Modify
