One of the most recurring and important use cases while adopting Solr or similar technologies is the ability to tune our language analysis components over one or more specific languages. Even if this may seem simple from a beginner's point of view, it introduces some complexity. In a real world scenario, we probably have to manage several different languages, each of them with its own specific configuration. This process of obtaining a good working configuration can consume a considerable amount of time, so you shouldn't underestimate that. Start with as simple configuration as possible, then take time to elaborate upon one aspect at a time, as we normally do. The first step in this path will be, needless to say, the identification of the language itself. Then, we could start adopting a very simple stemmer, just to give an idea on a general case.
