Attachments cannot be previewed if a page contains more than 100 attachments

What happens:

Pages that contains more than 100 attachments seems to break the indexing of the attachments. Searching for the 101st and above attachments does not seem to work

Steps to reproduce:

1. Create a new page,
2. Go to Tools > Attachment
3. Attach 104 PDFs
4. Copy the 101st PDF title (The 101st PDF is the first PDF listed in the 6th page)
   
5. Paste to the search bar, click on the suggested result
   ,
6. Confluence not able to preview this PDF:

   File can not be displayed
   Error: File does not exist
   

   

7. All PDF before the 100th (that is located in the 5th and below pages) are fine

What we have tried:

1. Rebuilding index from Admin console
2. Rebuilding index from scratch
3. Viewing the said PDF itself is fine
