Finder search and spotlight won't find partial words
Searching my mac won't find a file unless I use a complete word from the filename. For example, a search for "planet" won't find "planetoid.doc."
Both finder window and spotlight search have same results in Big Sur 11.2.3. Oddly, it does seem to work for file contents, just not names. So a search for "planet" would find the text "planetoid" inside a document.
Is there a way to change the settings? This makes it extremely difficult to find files when you can't remember exactly what an old file was named.
Thanks
