Impossible to delete doc by docId, undeleteAll or setNorm(docId..)
------------------------------------------------------------------
Key: LUCENE-3828
URL: https://issues.apache.org/jira/browse/LUCENE-3828
Project: Lucene - Java
Issue Type: Bug
Components: core/index
Affects Versions: 4.0
Reporter: Andrzej Bialecki
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.
