[SOLR-1915] DebugComponent should use NamedList to output Explanations instead of Explanation.toString() - Solr - [issue]
|
|
...DebugComponent currently uses Explanation.toString() to "format" score explanations for each document as plain text with whitespace indenting to denote the hierarchical relationship...
|
|
..., and then adds those explanations to the SolrQueryResponse.
Instead DebugComponent should transform the Explanation objects into NamedLists so that the full structure can be formatted in a logical way...
