Subject [jira] [Commented] (SOLR-3534) dismax and edismax should default to "df" when "qf" is absent.
Date Mon, 11 Jun 2012 21:39:43 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3534?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13293111#comment-13293111

Jack Krupansky commented on SOLR-3534:
--------------------------------------

Okay, but if df does not have a default value, then at least have it throw an exception at
an early stage, like core/handler load, rather than result in queries with an empty field
name that returns zero results as it does today.

Although, I suppose it is possible that a particular application may intend to set df explicitly
on each request and not need/want a default. But, even in that case, I think an exception
should be thrown rather than accept an empty field name and silently provide zero search results.

I am still in favor of "text" as the hardwired default. Isn't "text" the traditional default
search field? Including in the Solr example schema.

But, that said, I will certainly defer to the rest of the Solr community.

> The dismax and edismax query parsers should default to "df" when the "qf" parameter is
absent.  They only use the defaultSearchField in schema.xml as a fallback now.
