Yury Kats commented on SOLR-2724:
---------------------------------

FWIW, PingRequest fails if there is no defaultSearchField

CommonsHttpSolrServer#ping produces:

org.apache.solr.common.SolrException: Ping query caused exception: no field name specified
in query and no defaultSearchField defined in schema.xml

> I've always been surprised to see the <defaultSearchField> element and <solrQueryParser
defaultOperator="OR"/> defined in the schema.xml file since the first time I saw them.
 They just seem out of place to me since they are more query parser related than schema related.
But not only are they misplaced, I feel they shouldn't exist. For query parsers, we already
have a "df" parameter that works just fine, and explicit field references. And the default
lucene query operator should stay at OR -- if a particular query wants different behavior
then use q.op or simply use "OR".
> <similarity> Seems like something better placed in solrconfig.xml than in the schema.

> In my opinion, defaultSearchField and defaultOperator configuration elements should be
deprecated in Solr 3.x and removed in Solr 4.  And <similarity> should move to solrconfig.xml.
I am willing to do it, provided there is consensus on it of course.
