problems with search

[Cryptodarktrader]

Hello, I'm having problems when formalizing my search.

I have a series of notes that are basically information sheets of contacts contacts

They are in a folder called contacts inside another folder called social

In addition, all the files have the hidden link (in notes)

%%----------
[[contacts]]
----%

so I can locate them either by the folder path or by the link
My problem is that I want to group them in alphabetical order, A in A, B in B, and I can't get them to be grouped regardless of whether it is uppercase or lowercase.

I have this:

list file.name
FROM [[610 - 👥Contacts]]
where regexmatch("^d", file.name)
SORT file.name ascending
