Schema.xml(An Implementation similar to Compound Primary Key)?

And of course, when using DIH you can use templateTransformer and or regexTransformer to
merge field fragments to generate UID's

Some ideas:
- Use copyField to copy fields to the field designated as the uniqueKey (not sure if this will work)
- Create the field from existing data before sending docs to Solr
- Create a custom UpdateRequestProcessor that adds a field for each document it processes and stuffs it with other fields' values
- Try http://wiki.apache.org/solr/Deduplication
I'd be curious to know which of these you will choose.
