Solr: Introduce a custom field in solr query response

Is it possible to introduce a custom field in Solr QueryResponse that would contain a value that is computed based on another response value? For example if I have "score" field in the response, I want my custom field (let it be named "multipliedScore") to contain value = (score * 10);

The value of the custom field needs to be calculated (not static).

Maybe there's a way to take the score value calculated by Solr and multiply it or turn into a string with prefix/postfix (not asking here about turning it into percentages)?

You can achieve this using a DocTransformer . Just inherit from the class and implement the required logic in the transform method :

public void transform(SolrDocument doc, int docId) {
    String oldValue = doc.getFieldValue(fieldName);
    doc.put(newField,getNewValue(oldValue));
}
