Re: Contributors - Solr in Action Case Studies

Hello,
We've been working extensively with Solr as a 'standard' search service.
However, recently, we had a volume problem displaying time series (by
instance, sentiment of a brand by date), pulling data from a highly
denormalized database. Indexing a view of this database, coupled with
faceting (god bless faceting :D) by the date field, gave us directly every
data series we needed to display, in a time an order of magnitude faster
than the database (I guess the 'regular' way) approach. Roughly 1-2 seconds
'playing' with 300.000 points (Solr approach) vs nearly 45 seconds in the DB
approach.

Amazing thing is that we are not using Solr as a 'text' indexer. The
approach is more like a 'faceter' of data and it is surprisingly fast. Can
be a good case study of a non-standard way of using Solr or in the Solr vs
Database 'war' :D

>From now on, we're adopting this approach every time we have to display
Flash graphs of time series in front-end projects

Our field of work is mainly text crawling, analysis and indexing, including
sentiment analysis, focused crawling, natural language understanding,
concept extraction...

Thanks,

Oscar

This would be very welcome! I am interested in this particular use case. In
other words: if the book will contain this use case then you can count with
me buying this book! :-)

I'd be happy to contribute how we use Solr to power http://search.lucidimagination.com.  We ingest many different data sources (email, web, wiki, JIRA, source code, etc.) and use dismax, multi select faceting and a variety of other techniques.  I think it would make for a great case study.
