You must only reindex, if you *change* the Analyzers to different ones. If
you keep the old schemas and ensure that tokenizer luceneMatchVersion
settings keep alive, you don't need to.

So, in my case, upgrading from Solr 1.2 to 3.2, I must re-index. OK, I got
that, thanks.

 

Btw, where can I learn more about the "new IndexUpgrader tool"?  Is there a
doc/wiki for it?

Hi,

 

When analyzers change behavior you have to reindex, there is no way around.
The index-upgrader tool simply rewrites index segments to the new file
format, but does not change contents.

Hi,

 

Looking at  <http://wiki.apache.org/lucene-java/ReleaseNote32>
http://wiki.apache.org/lucene-java/ReleaseNote32, the item:

 

 * A new IndexUpgrader tool fully converts an old index to the
   current format.

Where can I learn more about this?  Is this for upgrading the Lucene index
from Lucene 2.1 to 3.2 due to the analyze change?

 

My question is around the fact that an index created using Solr 1.2 is not
compatible with Solr 3.2, and I'm trying to see if the above will solve my
problem or must I re-index.

 

Thanks in advanced !!!

 

-JM

Hello,
 
While we await the results of the vote (72 hours), I thought it would
be good to propose something new for the release emails, by putting
something up on the wiki where anyone can just edit it. In the past,
we would email each other back and forth and I think that's not the
easiest way to build up a document.
 
So, if you are motivated, please review and improve:
 
 <http://wiki.apache.org/lucene-java/ReleaseNote32>
http://wiki.apache.org/lucene-java/ReleaseNote32
 <http://wiki.apache.org/solr/ReleaseNote32>
http://wiki.apache.org/solr/ReleaseNote32
 
Again, this is a little premature and tentative since the vote still
has not passed, but it looks like it stands a good chance of doing so,
and it would be good to incorporate more feedback... these little
"marketing"-type things probably deserve more attention than we
normally give them.
 
Also for discussion: for the next release, we could consider copying
the templates to ReleaseNote33 and make these live documents that we
edit as we work towards the release, instead of at the end (we could
always fix them up at the end too). So if we add a really huge feature
we could add it when its actually committed.
