Subject [jira] Updated: (SOLR-1915) DebugComponent should use NamedList to output Explanations instead of Explanation.toString()
Date Tue, 25 May 2010 22:53:39 GMT

     [ https://issues.apache.org/jira/browse/SOLR-1915?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hoss Man updated SOLR-1915:
---------------------------

    Attachment: SOLR-1915.patch

patch making the necessary changes.

Just in case some poor soul was actually attempting to programmaticality parse the old "toString()"
response, i added a new "debug.explain.stringFormat=true" param to force the old behavior,
but the default is to be a structured response, and frankly i don't think we should even document
that param except in the upgrade section of CHANGES.txt (where i explicitly indicated that
it would be removed in the next release -- it should only be there as a red flag and a stop
gap in case people don't notice the change until it breaks something)

> 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 by the ResponseWriter
