Rails 3 Sunspot Fulltext Search Usage
问题 So I've implemented the sunspot_rails gem into my application to utilize the powerful Solr search engine. I recently checked out Ryan's railscast on full-text searching and I noticed he was using additional parameters in his search queries such as "-" to denote something that should NOT be including in the full-text search. I never heard about this until now, I was wondering if there was a user-friendly usage guide somewhere both me and my users can reference to take my search functionality
