Assuming that you import the data using the console, any data in the JSON file replaces the existing location where you run the import. There is no way to change this behavior.
What you can do is import the data to a different location in the console. So if you open the recipes
node to import the first JSON, and open the searches
node for the second JSON, the two imports won't overwrite each other.
If you want to import them into the root of the database, you'll have to merge the two JSON files yourself and then import them in one go.
