Windows 10: Indexing of a second drive (New Point)

In the recent topic Indexing of Second Drive Dalchina said:

"..... can you confirm that your problem is that you have specified folders to be indexed on your 2Tb drive, and that you can do that in Indexing Options in the Control Panel, but that when you add such locations, the number of indexed items does not increase (as shown in Indexing Options)?
If your symptom is different, please describe it as you see it in your new thread. If making reference to searching, please clearly discriminate between using file explorer and Cortana (screenshot if so). Thanks."

My problem is that files on my second, spinning, drive "General (D)"are never detected, and have never been detected, when I do a search for a file in the search bar next to the Start Button, despite the Window 10's window "Indexing Options including that drive (please see the first attachment).

This window is the same as it was when I bought this new computer 9 months ago (a Lenovo). I have never changed it. I can find a file which has been saved on the Desktop by entering it in the search bar, but not one saved in Downloads, nor any other file or folder on D drive.

I have always believed that a search entered into the search window should find all files on "General (D)". A Windows 10 site by Microsoft states:

"Type what you're looking for in the search box on the taskbar. You'll get suggestions and answers to your questions, and search results from your PC and the web."

A possible complexity (the only one in my computer that I have, no unusual Settings, adventurous software etc.) is that all Documents (and also music, Pictures etc.) have been redirected from the default Documents folder on my C: drive (an SSD) to the drive "General (D)". All those files can be found after manually entering them in the search bar on the window displaying the documents folder itself. Please see the second attachment.

Thanks for any insight here.

I have just done a re-indexing in the Indexing Options Control Panel. Entering a file name in the search box finds nothing on the computer. If I press the folder button which you highlighted, and enter a file name in the search box I get files contained only in my Documents folder (which is on D) even when files of the same name are in other folders such as Pictures, videos etc. I don't get those. So searching for a document is easy.

To find files in other folders, I can (as you mentioned) precede the search term in the search box with <folder name>, as in Music: <search term>. That finds the file. Alternatively, again as you mentioned, I can open in File Explorer the folder hopefully containing the file and enter the file name in its search box at the top right of the window. (Attachment):


That also finds the file.

I think I have come to the end of this investigation. I had thought the search box in the Task Bar would have been designed to search the whole computer, or some selected folders as an option (not just Documents). That would have been more convenient. However, I am able to find files one way or the other. I like Windows 10. Musn't grumble.

Thanks for your help.
