Since I never explicitly create the model myself, I have successfully specified the required database in the construction of my model, and the actual working code is shown below.
My component shows Blog articles from a different (Joomla 3) database that was too complex to convert. Users can search and display the articles from the current (Joomla 5) site, thus preserving the historical records that go back several years. The details of the external database are specified in the menu definition of what is otherwise a list that follows the usual paradigm.
As in many cases, once one has overcome the lack of documentation it is quite straightforward, but I would not have been able to solve the problem without the help and support offered by this Forum. I am most grateful.
