Schema API is the one-stop shop for most operations on your schema. It provides a REST-like HTTP API for doing all these operations.
You can read, write, or delete dynamic fields, fields, copy field rules, and field types.
Do not manually write any changes into the managed-schema file yourself. This will work only as long as you don't use Schema API. If you use Schema API by mistake, all your changes might be overwritten. So, it is highly recommend that you leave your managed-schema file alone.
The response of the API call is of either JSON or XML format.
Assuming that you are using the gettingstarted collection, the base address of API will be http://localhost:8983/solr/gettingstarted.
Always reindex once you use Schema API for modifications. Only then will the changes that you have applied to the schema be reflected...
