How to filter out old files

[QuAzI]

Is there any way to rg all files recursively, but only if they are not older than 3 days or 1 hour or changed between some period?

ripgrep doesn't have facilities for filtering by timestamp. It might grow them some day, but for now, you'll need to use some other tool. e.g., find ./ some-filter-options -print0 | xargs -0 rg pattern-to-search-for.
