solr - set fileds as default search field - solr

Question

The following query works well for me
http://[]:8983/solr/vault/select?q=VersionComments%3AWhite
returns all the documents where version comments includes White
I try to omit the field name and put it as a default value as follows :
In solr config I write
<requestHandler name="/select" class="solr.SearchHandler">
<!-- default values for query parameters can be specified, these
will be overridden by parameters in the request
-->
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<str name="df">PackageName</str>
<str name="df">Tag</str>
<str name="df">VersionComments</str>
<str name="df">VersionTag</str>
<str name="df">Description</str>
<str name="df">SKU</str>
<str name="df">SKUDesc</str>
</lst>
I restart the solr and create a full import.
Then I try using
http://[]:8983/solr/vault/select?q=White
(Where
http://[]:8983/solr/vault/select?q=VersionComments%3AWhite
still works)
But I dont get the document any as answer.
What am I doing wrong?

As far as I know you should only have the <str name="df"></str> declared once in your requestHandler
Typically what I do is copy all the fields that i want to search into a default search field called text.
schema.xml:
<copyField source="name_t" dest="text"/>
solrconfig.xml
<requestHandler name="/select" class="solr.SearchHandler">
<!-- default values for query parameters can be specified, these
will be overridden by parameters in the request
-->
<lst name="defaults">
<str name="q">*:*</str>
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<str name="df">text</str>
</lst>
</requestHandler>
If this is not good enough, you can always search other fields using a dismax search with the qf declaration like so:
http://localhost:8983/solr/vault/select/?q= White&defType=dismax&qf=PackageName+Tag+VersionComments+VersionTag+Description+SKU+SKUDesc
