| ## Separation of IndexDocument and StoredDocument (LUCENE-3312) |
| |
| The API of oal.document was restructured to differentiate between stored |
| documents and indexed documents. IndexReader.document(int) now returns |
| StoredDocument instead of Document. In most cases a simple replacement |
| of the return type is enough to upgrade. |
| |
| ## Removed Reader from Tokenizer constructor (LUCENE-5388) |
| |
| The constructor of Tokenizer no longer takes Reader, as this was a leftover |
| from before it was reusable. See the org.apache.lucene.analysis package |
| documentation for more details. |
