Unable to filter assets based on 'folders' option

[udayashankarc29]

Our authors want to filter the DAM based on path, type of file (file or folder)
Currently we have DAM folder under /content/dam where 'loose assets' and 'folders' exist together (I'm assuming that's a normal) under any given path. But with AEM's OOTB filter option in DAM, we can't seem to filter folders. 
- I go to filter under dam 

- then there are 3 options under path - files, folders, files & folder : 

Ónly 'Files' filter work and the other two doesn't seem to work. When I try to filter with 'Folders' - I see empty results, but we have loads of folders. Then I did the same in a 'vanilla' instance - plain 6.5 without any of our content and code, even there I see this problem : 

Is this a known issue ? Are we doin something wrong?

Upon checking errors - One commons trace in my vanilla instance as well as my equipped instance - is this :

I can reproduce the same issue on AEM SP 15 as well. It seems like a product bug to me. Please raise a Adobe Support ticket as the issue can be reproduced in vanilla instance as well.

As you mentioned, the indexing error logs are showing up on selection of any option from the dropdown(Files, Folders, Files & Folders).
