Export big extract from Solr to [My]SQL

[Per Steffensen]

Hi

I want to make extracts from my Solr to MySQL. Any tools around that can 
help med perform such a task? I find a lot about data-import from SQL 
when googling, but nothing about export/extract. It is not all of the 
data in Solr I need to extract. It is only documents that full fill a 
normal Solr query, but the number of documents fulfilling it will 
(potentially) be huge.
