Subject [jira] [Commented] (SOLR-2599) FieldCopy Update Processor
Date Wed, 05 Oct 2011 18:26:29 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13121327#comment-13121327
] 

Jan Høydahl commented on SOLR-2599:
-----------------------------------

Perhaps {{multival}} should be renamed {{multiValued}} to comply with schema lingo?

Also, if I make it (optionally) schema aware, I can set {{multiValued}} behavior as default
if {{dest}} field is multivalued. Also, perhaps it makes sense to allow {{append}} for {{multiValued}}
as well, and let it append all {{source}} fields to a string, and then adding this concatenated
string as one single field value instead of each {{source}} as its own value?

The reason I want to be able to disable strict schema checking is in the case where a processor
creates intermediate fields only, which we know will be removed from {{SolrInputDocument}}
before indexing, so that we can be free to name it whatever we like without causing an error.
Unfortunately, {{ExtractingRequestHandler}} is too strict here and would benefit from a {{enforceSchema=false}}
option.
