: I've been mulling over the idea of having a single Solr instance : morph into system that can handle multiple client-defined schemas : (why not? Lucene itself can handle it) rather than a static XML file : and allow the schemas themselves to be retrievable (yes, I know it : already is). I'm still talking about a single Lucene index, but with : each Document given a "soup" name field and filters automatically : available to single out a specific soup.
Given the flexability of dynamicFields, i think we're 99% of the way there -- all we'd need is support for <copyField source="*_t" dest="foo"/> and then you could define a "soup" schema with nothing but dynamic fields (one per datatype/stored/index triple you care about) and a few common fields for partitioning and generic text searching. -Hoss
