Oh, maybe you just had `gnus-search-use-parsed-queries' set to nil. One
way or another, the query must not be getting parsed. But that's fine!

This just means that when namazu returns its search results, this
function fails to find a filename. In other words, the (match-string 4)
returns nil.

(cl-defmethod gnus-search-indexed-extract ((_engine gnus-search-namazu))
  "Extract a single message result for Namazu.
Namazu provides a little more information, for instance a score."

  (when (re-search-forward
	 "^\\([0-9,]+\\.\\).*\\((score: \\([0-9]+\\)\\))\n\\([^ ]+\\)"
	 nil t)
    (forward-line 1)
    (list (match-string 4)
	  (match-string 3))))

Using the example results that you send me (the bash script) the file
names are found correctly. Is there a way you can find and show me the
filename that isn't being found by this regexp? I assume it's a filename
that doesn't start with a digit. I'm not sure where this regexp came
from, originally.
