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.
> Explain doesn't deal with negative only queries completely correctly

> 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).
