Thanks Andy!
Everything should work as before. So faceting, function queries, query
boosting should still work.
For eg:
q=name:efghij^2.2 name:abcd^3.2
returns all docs with name efghij and abcd but ranking documents named
abcd above efghij

Nagendra,
This looks interesting. Does Solr-RA support:
1) facet
2) Boost query such as {!boost b=log(popularity)}foo
Thanks
Andy

Hi Andy:
I have a solution for NRT with Solr 1.4.1. The solution
uses the RankingAlgorithm as the search library. The NRT
functionality allows you to add documents without the
IndexSearchers being closed or caches being cleared. A
commit is not needed with the document update. Searches can
run concurrently with document updates. No changes are
needed except for enabling the NRT through solrconfig.xml.
The performance is about 262 TPS (document adds) on a
dual core intel system with 2GB heap with searches in
parallel. The performance at the moment is limited by how
fast IndexWriter.getReader() performs.
I have a white paper that describes NRT in details, allows
you to download the tweets, schema and solrconfig.xml files.
You can access the white paper from here:
http://solr-ra.tgels.com/papers/solr-ra_real_time_search.pdf
You can download Solr with RankingAlgorithm (Solr-RA) from
here:
http://solr-ra.tgels.com
I still have not yet integrated the NRT with Solr 3.1 (the
new release) and plan to do so very soon.
Please let me know if you need any more info.

Hi,
I read on this mailing list previously that NRT was
implemented in 4.0, it just wasn't ready for
production yet. Then I looked at the wiki
(http://wiki.apache.org/solr/NearRealtimeSearch). It
listed 2 jira issues related to NRT: SOLR-1308 and
SOLR-1278. Both issues have their resolutions set to "Won't
Fix" recently.
Does that mean NRT is no longer going to happen?
What's the state of NRT in Solr?
Thanks
Andy
