How to get a list of files starting with the year

[dingsw1]

There are a lot of files, and I want to filter all the files starting with the year (e.g. 1987, 2003, 2020, etc.) by dataview, but I'm not sure how to do it.

table without id
file.link
where
file.day.year = "2020"

should get you started. In case this doesn't help, can you paste here a few examples of your filenames?

A partial list of documents is as follows：
1993 8378822Emb……
1992 1521659 Un……
1990 2138432 et……
1980 7381667The……
1979 437165 Epi……
1969 5779274The……
2005 周欣 腹腔镜……
other file1
other file2
file3
I want to filter the list of all documents starting with the year except the last three

I have an idea to detect if the first four characters of a file name are numbers, but I don't know how to do it with dataview, can you help me? Thank you very much!

See: https://blacksmithgu.github.io/obsidian-dataview/query/functions/#regexmatchpattern-string

You'd probably want to do something like regexmatch("^\d\d\d\d", file.name).

In fact, for a specific year, you could directly use startswith("2005", file.name)

This works very well, and thank you very much!
