Hi David:

Did you have a chance to see my comments in the JIRA ?

Nagendra,

I'm surprised to see you're still promoting your realtime-search based
system given the critical problem that Yonik found:
https://issues.apache.org/jira/browse/SOLR-3816?focusedCommentId=13494815&p
age=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#commen
t-13494815

That is a serious fundamental flaw, I'm sorry to say.  To quote Yonik:
"You'll get incorrect documents back, incorrect facets back, pretty much
any number of random looking bugs because internal docids will be changing
underneath you."   This won't necessarily happen all the time depending on
the timing of the search with respect to concurrent changes, but it can
happen.

Hi:

I am very excited to announce the availability of Apache Solr 3.6.2 with
RankingAlgorithm30 1.4.3 with realtime-search support. realtime-search
is very fast NRT and allows you to not only lookup a document by id but
also allows you to search in realtime, see
http://tgels.org/realtime-nrt.jsp. The update performance is about
10,000 docs / sec. The query performance is in ms, allows you to  query
a 10m wikipedia index (complete index) in <50 ms.

This release also includes a experimental TimedSerialMergeScheduler
<http://rankingalgorithm.1050964.n5.nabble.com/TimedSerialMergerScheduler-
java-allows-merges-to-be-deferred-to-a-known-time-like-11pm-or-1am-tp57063
50.html> that
allows you to postpone your merges to off hours time like 11pm or 1am
increasing performance.

RankingAlgorithm30 1.4.3 supports the entire Lucene Query Syntax, ±
and/or boolean queries.

You can get more information about realtime-search performance from here:
http://solr-ra.tgels.org/wiki/en/Near_Real_Time_Search_ver3.x

You can download Solr 3.6.2 with RankingAlgorithm30 1.4.3 from here:
http://solr-ra.tgels.org

Please download and give the new version a try.

Note:
1. Apache Solr 3.6.2 with RankingAlgorithm30 1.4.3 is an external project.
2. realtime-search has been contributed back to Apache Solr, see
https://issues.apache.org/jira/browse/SOLR-3816
