Subject [jira] [Commented] (SOLR-2724) Deprecate defaultSearchField and defaultOperator defined in schema.xml
Date Fri, 15 Jun 2012 20:32:43 GMT


Jack Krupansky commented on SOLR-2724:

As with SOLR-3534, I think it would be helpful to users and ease the support burden if we
added a warning to the comment for the deprecated <defaultSchemaField>  that says "WARNING:
The "df" query request parameter, including the default in any query request handlers, overide
this default search field. So, before uncommenting this deprecated element, be sure to review
how "df" may be used in relevant request handlers in such a way as to override this deprecated
default search field."

> 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.
