checking Duplicates when indexing

[Stamimail]

I do not know if "Duplicates in Resuls List" is still a common question or not.
If so, I suggest doing a test before and after indexing.
And if there are duplicates in the list of results, inform the user about it, and offer him what to do.

I found that the "Index Type" property can help us to understand where the duplications come from.

Duplicated results usually occurs when the user adds an NTFS volume to Tools -> Options -> Folders.

I am considering showing a warning when trying to add an NTFS volume to Tools -> Options -> Folders

I will consider checking the index for duplicates and suggesting actions to the user.
Thank you for the suggestion.
