Search application development can start the moment you download Solr. As you ingest your data, or a sample thereof, you can easily see the search results in a familiar search user interface. Want to facet on a field? Done. Want to full-text search on a field? Change some configuration, restart, reindex, and voila! Done right, the iterative process of development and discovery will help you better match users to the data they need and deliver a quality search experience.
