------------------------------
Attachment: SOLR-2599.patch
Here's the processor. It's been in production for some time at a customer.
Sample config as follows:
{code}
<processor class="solr.FieldCopyProcessorFactory">
<str name="source">category</str>
<str name="dest">category_s</str>
</processor>
{code}
To move (rename) a field:
{code}
<processor class="solr.FieldCopyProcessorFactory">
<str name="source">LastModified</str>
<str name="dest">last_modified</str>
<bool name="move">true</bool>
</processor>
{code}
To append to existing field:
{code}
<processor class="solr.FieldCopyProcessorFactory">
<str name="source">lastname firstname</str>
<str name="dest">fullname</str>
<bool name="append">true</bool>
<str name="append.delim">, </str>
</processor>
{code}
To append as values to multivalued field, with optional size cap:
{code}
<processor class="solr.FieldCopyProcessorFactory">
<str name="source">title body</str>
<str name="dest">text</str>
<bool name="multival">true</bool>
<int name="maxChars">100</int>
</processor>
{code}
