Put the following in your Gemfile:

gem 'mongo_mapper'
gem 'sunspot_mongo'

Then run:

rails g mongo_mapper:config
rails g sunspot_rails:install
rake sunspot:solr:start

gem 'mongoid'
gem 'sunspot_mongo'

Then run:

rails g mongoid:config
rails g sunspot_rails:install
rake sunspot:solr:start

When upgrading to a new version, don't forget to check UPGRADING for notes about breaking changes.

Add the following to your model (assuming you have a string field named "content"):

include Sunspot::Mongo
searchable do
  text :content
end

Then search like usual:

search = Article.search do
  fulltext "something interesting"
end
search.results

Note: Mongoid adds Article.search, use Article.solr_search instead.

If you are using Rails, objects are automatically indexed to Solr as a part of the save callbacks.

You can reindex a collection by calling .reindex directly on the model class. When using Mongoid, #reindex can be called on a search scope or criteria, reindexing only the matching objects.

Article.reindex

# Mongoid only
Article.pending.reindex
Article.where(status: "posted").reindex

Note: #reindex on a MongoMapper search will always reindex the entire collection.

If you make a change to the object's "schema" (code in the searchable block), you must reindex all objects so the changes are reflected in Solr. Run:

bundle exec rake sunspot:reindex

See the Sunspot documentation.
