Thanks for the clarification.
This is a hefty limitation of the Lucene.
One would expect, that you would be able to update a specific field in
the index without having to reindex the entire document.

You can retrieve the raw content for each field (assuming you stored it).
But then you must re-generate a Document from the raw content
yourself, as you did originally.
Ie you cannot rely on Lucene to remember schema-like things like
boost, the FieldType (how the postings were indexed, whether term
vectors were indexed, etc.).

How do you update a document that resides in the index without having the
original document?

How did you produce the document that you are sending to
updateDocument? Are you loading it from IndexReader.document() or
IndexSearcher.doc(), changing it, then passing that to
IW.updateDocument? If so, that's probably your bug: a loaded document
is not identical to the original Document you indexed. In 5.0 we've
fixed this to be strongly typed ...

Greetings
I am using Lucene NRT search. After calling writer.updateDocument(term,
doc)
and then search(), the document is no longer visible in the search
results.
The program must be restarted to see it again. In addition, the update is
not being applied. The original document (before the update) is visible
in
the search results. If updateDocument(term,doc) is called, passing the
original doc (without any changes), the doc is still removed from the
index
(i.e. the change is not the cause). On each search I am calling
indexReader
= DirectoryReader.open(writer, true); We have tried to call commit()
and/or
close() immediately after the update, but it makes no difference.
This occurs both in Lucene 4.7.2 and 4.8. As far as we know, our code
used
to work with prior versions of Lucene. Has anyone encountered this?
