Sunspot Stats

Sunspot is a Ruby library for expressive, powerful interaction with the Solr search engine. I use the latest version 2.0.0.pre.120417 but i need the statsComponent in order to get the sum on a given indexed field.


Add this line to your application's Gemfile:

gem 'sunspot_stats'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sunspot_stats


The statComponent let you to have min, max, count, missing, sum, sumOfsquare, mean and stdev.

An usage example do
  stat(:your_field, :facet => :your_facet_filed, :type => "min")  

:facet and :type are optional the default type is the "sum" (you can pass: min, max, count, missing, sum, sumOfsquare, mean, stdev as string)

Remember to stats on a non multi valued field and update to the solr3.6, because the solr3.5 has a bug with stats.

the Sunspot::SearchStatRow has the method stat_field and the value.

If you enable faceting on stats the stat_field is the facet and the value is the type defined.

Boolean Searches

Usually Suspot use the dismax for searches, here we extend to edismax to manage also boolean logic searches

a OR (b AND c) works.
