Setting Up PGroonga for Full-Text Search in Elixir Projects

The article describes the steps needed to implement full-text search in Elixir applications using the PGroonga extension for PostgreSQL. Initially, the reader is guided through the installation process, which can be done using a Docker image, through a database provider's interface like Supabase, or by manual installation. After installing, one must create a new migration in their Elixir project to enable the PGroonga extension in their database. Following that, an index is created on the necessary text column, like a transcript, to optimize search queries. The article also includes an example Ecto query, which demonstrates how to perform a full-text search and retrieve highlighted matches with context for a given search term. It concludes with a brief mention of how to display these search results in a Phoenix application, along with a cautionary note about user-input sanitization to prevent XSS attacks.
