Subject [jira] [Commented] (SOLR-2636) Explain doesn't deal with negative only queries completely correctly
Date Wed, 06 Jul 2011 00:44:16 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2636?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13060220#comment-13060220
] 

Tom Hill commented on SOLR-2636:
--------------------------------

@hoss Shall I close this one?

@yonik Would it make sense for SolrQueryParser to just call makeQueryable?

  @Override
  public Query parse(String query) throws ParseException {
    return QueryUtils.makeQueryable(super.parse(query));
  }

Then the other three calls to makeQueryable can be deleted, I think. And it fixes the problem
with expain.

> If you do a negative only query, such as -author:[* TO *], explain returns NaN for the
score. The query executes correctly, however.
> To execute negative only queries, Solr calls QueryUtils.makeQueryable, and everything
works correctly. But explain doesn't call this, and coord ends up dividing by zero.
> One could fix this by fixing the call to explain, which is easy, or perhaps by fixing
the query parser to generate the query that way in the first place. (It looks like extended
dismax does the latter, and so shouldn't have problems).
