TV app in Catalina does not search in local library Actually problem/issue pointed in the title of the question.
When I try to search something in the search field in the up right corner app just shows results from the store, not local library. 

As a result I cannot find my own movies.
Anybody can confirm such behaviour?
Can give a hint for workaround/fix?
Use the Show Filter Field option to search your library:


Click Library at the top of the window
Click View in the menubar and select Show Filter Field
Use the filter field to search your library
