LTR - FieldValueFeature Question

Hi everybody,

Do we need to have 'indexed=true' to be able to retrieve the value of a
field via FieldValueFeature or is having docValue=true enough?

Currently, we have some dynamic fields as [dynamicField=true, stored=false,
indexed=false, docValue=true]. However when we noticing that the value
extracted is '0.0'.

This is the code I read around FieldFeatureValue:
https://github.com/apache/lucene-solr/blob/master/solr/contrib/ltr/src/java/org/apache/solr/ltr/feature/FieldValueFeature.java

Thanks,

Ash

It seems that in order to be available for FieldValueFeature score calculation, the field should be 'stored', otherwise it is not present in the document. It is also seems that indexed/docValue does not matter:

          final IndexableField indexableField = document.getField(field);
          if (indexableField == null) {
            return getDefaultValue();
          }
