April 2013, Apache Solr™ 4.2.1 available
The Lucene PMC is pleased to announce the release of Apache Solr 4.2.1
Solr is the popular, blazing fast, open source NoSQL search platform
from the Apache Lucene project. Its major features include powerful
full-text search, hit highlighting, faceted searc
It was def intentional to make it default to true, but I believe that was

4.2 and 4.2.1 have collection aliasing (similar to what we had with SolrCore
aliasing at one point). You can use that to have one url and swap the
collection search by it by the scenes.

Leaders don't have much to do with querying - the node that you query will
determine what other nodes it has to query to search the whole index and do a

You should be able to simply use the ZkCli clear cmd:

The ZkCli cmd line tool allows you to pull config down too - so just pull the

Alternatively, there may be ZK UI tools that let you do this if you look.

When Solr loses it's connection to ZooKeeper, updates will start being

Yes, this did change - it's actually a protection for a previous change though.
There was a time when you did a core reload by just making a new core with the

I think that is the best way to deal with OOM's. Other than that, you have to

It will take a short bit of a time before a new leader takes over when a leader
goes - that's expected - how long it takes will vary. Some things will do short
little retries to kind of deal with this, but you are alerted those updates
failed, so you have to deal with that as you would other upd
This is a safety mechanism - you can turn it off by configuring leaderVoteWait
to 0 in solr.xml.
This is meant to protect the case where you stop a shard or it fails and then
the first node to get started back up has stale data - you don't want it to
just become the leader. So we wait to see ev
For those that would like to start diving in, I've started documenting the

own code, but we have not yet done this in trunk. What that places the upper
limit at, I don't know - I imagine it takes quite a few shards before it ends
