Omitting norms and the like only matters for text fields, primitives (numerics,
boolean, string) don’t have any of that information.
You really have no choice but to re-index to jump from 4->7. Or, I should say
you’re completely unsupported and you will have to deal with any anomalies. I

Thanks Erik for your answer.
Unfortunately I should migrate the index for time reasons. Maybe in a
second moment we will have the opportunity to reindex.
Our use case is to classify documents in the index with lucene queries,
hence we're not really interested in ranking or sorting (which could be

This is actually a problem. IndexUpgraderTool creates a single massive seg
How we would do it:
- update the index format to v7 (this in itself is fiddly
but there are ways)
- open the index in-place migrated:
- get all the leaf indices and wrap each in a new
subclass of FilterCodecReader
- override getPointsReader() on that subclass

Ok,
I know this policy and you perfectly explained why it makes sense.
Anyway my index is really big and contains mostly textual data which are
expensive to reindex (because of custom analysis).
Considering that the IndexUpgrader will efficiently do the most of the work
I should investigate how
You cannot upgrade more than one major version, you must re-index from scratch.
There’s a long discussion of why, but basically it’s summed up by this quote
from Robert Muir:
“I think the key issue here is Lucene is an index not a database. Because it is
a lossy index and does not retain all of
Hello everybody,
I have a (very big) lucene 4 index with documents using IntField. On that
field, which should be stored and sortable, I should search and execute
range queries.
I've tried to upgrade it from 4 to 7 with IndexUpgrader but I observed that
IntFields aren't searchable anymore.
