How to modify literal.id to literal.{xxx}

Question

I am trying to modify "literal.id" to "literal.docId", "literal.aa" and so on. because I want to change the uniqueKey like docId or another name to understand easily. the id is too simple. :D But for this, most documents and web pages I have searched have mentioned "The literal.id={value} param provides the necessary unique id for the document being indexed"

If someone knew how to do it, plz give me some hints, tips or answers.

Thank you.

When you upload a pdf to Solr, it populates Solr with

1. values extracted by Tika and mapped to Solr fields: content and author_name in the schema are filled like this
2. values given as parameters: literal.fieldxy gets mapped to fieldxy in Solr schema

In your case, your solr schema uses a field id for uniqueness. Hence the need to specify a literal.id for each upload. If you create a core with a different ID scheme, be sure to include a literal.idfield for each upload.
