SolrCollection is a wrapper for acts_as_solr results sets that behaves/feels like will_paginate collection

• no need to separate results from facets / spellcheck information
• all pages can use the same pagination helpers
• simple to mock an empty result when solr is down or throws errors

Usage

• As Rails plugin script/plugin install git://github.com/grosser/solr_collection.git
• As gem sudo gem install solr_collection

Example:

options = {:limit=>10, :offset=>100, :facets=>{....}, .... }
results = MyModel.find_by_solr("abc", options) rescue []
results = SolrCollection.new(results, options)

do_something if results.facets
something_else if results.total_entries > results.size #more pages ?
will_paginate(results)

Other features:

#facet fields can be nil or [] or {} -> use has_facet_fields? to check
puts results.facets['facet_fields']['categories'] if results.has_facet_fields?
