Affects Version/s: 4.0-ALPHA
Fix Version/s: None
It appears that there is a major regression in the trunk API. It's no longer possible to:
1. delete document by internal id (even though you can iterate and retrieve docs by internal ids)
2. undelete all deleted (but not yet reclaimed) documents
3. set norm value on a specific document (by internal id)
The lack of #1 means that you have to use delete by term or by query, which in turn means that now we require that documents have a unique primary key (otherwise you won't be able to delete a particular document that shares terms with other docs). IMHO this item is critical and should be fixed.
The lack of #2 might not be critical but it still comes handy in some situations.
The lack of #3 means that you have to update the whole doc if you just want to correct one field, which might be ok for the time being - it's a special case of not having updateable fields in general. But it's quite inconvenient if all you want to do is to adjust a weight of doc without reindexing, something that is possible with 3.x.
