This plugin provides the search feature for the main site.
It has support for using a variety of backends to power the actual searching, but currently only the default search backend (pg_search) is implemented. This is powered by the pg_search gem.
There is some stub code showing where support for Algolia (Search as a Service) could be added next, but no actual implementation.
Integration with other features
Models in other plugins (and the main app) can provide a template for rendering themselves as a search result, which this plugin will look for and use if/when that model comes up in the results for a search.
