Today I tried to upgrade a Lucene 4.10 index to 5.2 using the IndexUpgrader.
This throws the following exception:
Exception in thread Lucene Merge Thread #0
org.apache.lucene.index.MergePolicy$MergeException:
org.apache.lucene.index.IndexFormatTooOldException: Format version is
not supported
in this case (we are using MMapDirectory)?
Is there a way to cleanly abort a running search?

Thank you, that helped me a lot.

If the default DocValuesFormat isn't fast enough, you can always
switch to e.g. DirectDocValuesFormat (uses lots of RAM but it just an
array lookup).

Hi,
what is the best way
as long as no
document is deleted and the index optimized after it.
Is this a good solution or should we use Fields or DocValues for this?
What is the fastest solution?

8. If I am
not wrong, the above would mean that the document from B with score 8
can be a better match than the document from A with score 10.
Is that right?
If so, what can I do to make the scores from multiple indices comparable?

Hello,
does Lucene provide a zero or one character wildcard (like ? in Perl RegEx)?
Example of what I mean:
house% finds house and houses
As far as I know in Lucene the ? wildcard is for exactly one character,
but I need a zero or one character wildcard.
Best regards,
