The default site search has various limitations, especially when there is a vast amount of content with diverse applications. When products, blog posts, promotional content and member content all appears within a search, the results are challenging to wade through. Even to get to that point, Drupal builds an enormous table in the database. Backing up that data and rebuilding the index have both created problems in my specific use case. To address these problems (and some other shortcomings), I installed the Facet API and Solr modules.
