Hi Andy:
Here is a white paper that shows screenshots of faceting working with
Solr and RankingAlgorithm under NRT:
http://solr-ra.tgels.com/wiki/en/Near_Real_Time_Search
The implementation (src) is also available with the download and is
described in the below document:
http://solr-ra.tgels.com/papers/NRT_Solr_RankingAlgorithm.pdf
The faceting test was done with the mbartists demo from the book,
Solr-14-Enterprise-Search-Server and is approx around 390k docs.

Hi,
I need to provide NRT search with faceting. Been looking at the options out
there. Wondered if anyone could clarify some questions I have and perhaps share
your NRT experiences.
The various NRT options:
1) Solr
-Solr doesn't have NRT, yet. What is the expected time frame for NRT? Is it a
few months or more like a year?
-How would Solr faceting work with NRT? My understanding is that faceting in
Solr relies on caching, which doesn't go well with NRT updates. When NRT
arrives, would facet performance take a huge drop when using with NRT because
of this caching issue?
2) ElasticSearch
-ES supports NRT so that's great. Does anyone have experiences with ES that
they could share? Does faceting work with NRT in ES? Any Solr features that are
missing in ES?
3) Solr-RA
-Read in this list about Solr-RA, which has NRT support. Has anyone used it?
Can you share your experiences?
-Again not sure if facet would work with Solr-RA NRT. Solr-RA is based on Solr,
so faceting in Solr-RA relies on caching I suppose. Does NRT affect facet
performance?
4) Zoie plugin for Solr
-Zoie is a NRT search library. I tried but couldn't get the Zoie plugin to work
with Solr. Always got the error message of opening too many Searchers. Has
anyone got this to work?
Any other options?
Thanks
Andy
