/**
 * The files under `under` Drive full-text search names. The folder is walked
 * by id and Drive is asked which files in the walked folders hold the text.
 * Null when a listing or the search fails or times out, nothing is found,
 * Drive skips a corpus, or the scope is not a folder.
 *
 * Drive searches the text it extracted, not the bytes grep reads, so the
 * answer can leave out a file that holds the text: a Docs, Sheets or Slides
 * file (its JSON keys and ids), an office file, PDF or archive, the end of a
 * large file, a word Drive splits differently (`foo.bar`), or a recent write.
 * Mirrors Python's `files_containing`.
