The search function in the template manager (see screenshot) does only find *filenames* that *start* with exactly the search term.
First, it would be nice, if a template would also be found, if the search term occurs *inside* the filename and not only at the beginning.
Second, it would be very comfortable, if the search term would not only be searched for in *filenames* but also in document properties (metadata).

A screenshot of the template manager.
just retried with
Version: 18.104.22.168 (x64)
CPU-Threads: 2; BS-Version: Windows 6.1; UI-Render: Standard;
Gebietsschema: de-DE (de_DE)
and the bug still (or again) exists as described above - so REOPENED.
This has been fixed in the new template manager introduced in 5.2, which wont be there in 5.1.
