[jira] [Commented] (SOLR-9672) When using a mutilvalued field(fieldname) in fl an error appears

["Alexandre Rafalovitch (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-9672?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15592995#comment-15592995 ] 

Alexandre Rafalovitch commented on SOLR-9672:
---------------------------------------------

This would have been better asked on the User Mailing list. Because, as far as I can tell, you have multivalued docvalues and the field documentation says for those cases:
{noformat}
In it's simplest (single argument) form, this function can only be used on single valued fields..... For multivalued docValues fields: field(myMultiValuedFloatField,min)
{noformat}

But that's for numerics. I am not sure whether docValues support for multiValued strings would work here. But on mailing list, more people would see your question.

> When using a schema.xml with a field marked as multiValued, e.g.:
> <field name="frbr_Image-image"  type="string"  indexed="true"  stored="true"  multiValued="true"  />
> this error occurs:
> "an not use FieldCache on multivalued field: frbr_Image-image",
> when the field is requested in the fl parameter and wrapped in the field() syntax, i.e.:
> fl=field(frbr_Image-image)
> Full url:   http://localhost:8983/solr/manifestations_stage/select?fl=field(frbr_Image-image)&q=*:*
> When you remove the field() syntax the error doesn't occur and the correct values are returned. This occurs even if the fieldname doesn't need to be wrapped.
> I'm mostly using the default solrconfig.xml file (with a few lines taken out)
