What is the minimum Apache Solr core configuration required to run successfully?

Question

Solr

Good afternoon, there is Apache Solr 7.5
It will index data from the database.
When the core is created through the console (solr create -c mycore)
Then a certain standard universal core is created, with a bunch of localization files for stopwords into various languages, many types of fields are created in the schema, etc. etc.
How can you create, or maybe from somewhere you can take a minimally configured configuration, but already ready for work.
That is, I mean that, let's say in this setting there were not all these files in the lang folder, or there was only one, let's say for the English language, managed-schema was already schema.xml, with a minimum set of settings.
It is difficult to immediately navigate the configuration logic in such an abundance of files and field types.
Or maybe you don’t need to do this at all and it’s wrong to cut the default setting.
