Sunspot Stats

Sunspot is a Ruby library for expressive, powerful interaction with the Solr search engine. I use the latest version 2.1.0 but i need the statsComponent in order to get the sum (min, max, count, sumOfSquares, mean, stddev) on a given indexed field.

Installation

Add this line to your application's Gemfile:

gem 'sunspot_stats'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sunspot_stats

Usage

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

An usage example

Model.search do
  #Filters
	...
  #Facets
  ...
	#Stats
  stat(:your_field, :facet => :your_facet_filed, :type => "min")  
  ...
end

: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.

Upgrade solr in sunspot

StatsComponent Notes

The facet field can be selectively applied. That is if you want stats on field "A" and "B", you can facet a on "X" and B on "Y" using &stats.field=A&f.A.stats.facet=X&stats.field=B&f.B.stats.facet=Y

Warning, as implemented, all facet results are returned, be careful what fields you ask for!

Multi-valued fields and facets may be slow.
