For darktable tags, you can select partial tags by using '%' as a wildcard, so you could search %Thunder% in your example to get all of those tags. If the tag you are referring to is embedded in the EXIF data rather than being applied in darktable, I don't know if the wildcard will work, but it would be worth a try.
