Re: LTR - FieldValueFeature Question

[Dmitry Paramzin]

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();
  }

LTR - FieldValueFeature Question

[Ashwin Ramesh]

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
