Laravel Solarium how to add csv file to Solr core?

I am trying to make a laravel project. Users can upload a csv file to Solr via Laravel. I am already connect solr and can upload a csv file. But i dont know how to add the csv file to solr's core. Any suggestions, what should i do ?

If you want to index the csv info in Solr you have two options:

• Send the info using a "update" request handler. More info here
• Use Solarium functions to add documents. Some examples here and Solarium Documents documentations here
