Shai Erera commented on LUCENE-2310:
------------------------------------
Right Earwin - agreed.
I'd like to summarize a brief discussion we had on IRC around that:
The idea is not to provide another interface/class for search purposes, but
rather expose the right API from IndexReader, even if it might be a bit
low-level. API like getIndexedFields(docId) and getStorefFields(docId), both
optionally take a FieldSelector, should allow the application to re-construct
its Indexable however it wants. And IR/IS don't need to know anything about
that.
To complete the picture for current users, we can have a static reconstruct()
on Document which takes IR, docId and FieldSelector ...
BTW, I'm not even sure getIndedxedFields can be efficiently supported today.
Just listing it here for completeness.

> In order to move field type like functionality into its own class, we really
> need to try to tackle the hierarchy of Fieldable, AbstractField and Field.
> Currently AbstractField depends on Field, and does not provide much more
> functionality that storing fields, most of which are being moved over to
> FieldType. Therefore it seems ideal to try to deprecate AbstractField (and
> possible Fieldable), moving much of the functionality into Field and
> FieldType.
