I think the problem is that Baloo does not assign the file any category, and
consequently it won't show up in the file search results that specifically
query the individual categories in the code you linked to.
Note the information in Terms:
> $ touch myfile.foobar
> $ balooshow -x myfile.foobar
> 94995300010303 66307 9738579 yourfile.foobar [/home/natalie/myfile.foobar]
> Mtime: 1660051514 2022-08-09T15:25:14
> Ctime: 1660051514 2022-08-09T15:25:14
>
> Internal Info
> Terms: Mapplication Moctet Mstream
> File Name Terms: Ffoobar Fmyfile
> XAttr Terms:
As opposed to a .txt file:
> $ touch theirfile.txt
> $balooshow -x theirfile.txt
> 94984b00010303 66307 9738315 test.foobar [/home/natalie/theirfile.txt]
> Mtime: 1660050158 2022-08-09T15:02:38

> XAttr Terms:
"T5" and "T8" indicate categories Document and Text, see
https://invent.kde.org/frameworks/kfilemetadata/-/blob/master/src/types.h#L20.
"Mplain" and "Mtext" indicate the mime type.
> file --mime-type theirfile.txt
> theirfile.txt text/plain
When a file is created empty with an unknown file extension, it gets mime type
"inode/x-empty":
> $ file --mime-type myfile.foobar
> myfile.foobar: inode/x-empty
This does not get mapped to any category by Baloo:
https://github.com/KDE/baloo/blob/509dcd8da6b2e21723838f27003ac72d9a267a1a/src/file/basicindexingjob.cpp#L63
When the file has text content, even with an unknown file extension, it gets
mime type "text/plain":
> $ echo "test" > myfile.foobar
> $ file --mime-type myfile.foobar
> myfile.foobar: text/plain
But for some reason Baloo does not represent this in the term information, the
*.foobar has mime type ("M") "application/octet/stream" and no categories
("T"), even if the file is created non-empty and has mime type text/plain to
begin with.
So something seems to go wrong already on the side of Baloo for not setting the
terms information correctly.
But independently of that, it may be useful to be able to also retrieve results
that do not have any category. Either an additional query in the runner for
Baloo results with empty type, if such a query is possible. Or by adding to
Baloo a generic fallback type for any file that has not received any other
type, and adding that in the runner.
