Context: Why Local Music Libraries Matter

The initial context of this discussion stems from a growing lack of confidence in streaming platforms like YouTube and SoundCloud. These platforms, while vast in their catalogs, often fall short in providing a reliable and consistent experience, especially when it comes to specific music preferences or less mainstream content. The decision to prioritize a local music library reflects a desire for greater control, ownership, and a more curated listening experience. Local libraries allow users to organize their music according to their own tastes, ensuring that their favorite tracks are always accessible, regardless of internet connectivity or platform policies. This shift towards local storage necessitates a powerful search engine capable of handling diverse music collections and providing accurate results.

Lavalink, a popular library for streaming music, relies on public APIs for search engine functionality when dealing with platforms like YouTube and SoundCloud. However, this approach does not translate well to local music libraries. The absence of a comparable search mechanism for local files creates a significant gap in functionality, leading to a subpar user experience. To bridge this gap, a dedicated search engine for local music is essential. This engine should not only replicate the search capabilities offered by streaming services but also enhance them by leveraging the unique characteristics of local music collections, such as detailed tag data and file metadata. This underscores the importance of selecting a search engine that can seamlessly integrate with local libraries and provide a comprehensive and intuitive search experience.

Goals: Defining the Ideal Search Engine

The primary goal is to equip the bot with a feature-rich search engine for its local music library. This engine should utilize generic tag data and indexing to deliver a full-text search capability that meets several key criteria. First and foremost, it must support both English and Polish languages, catering to a diverse user base. The ability to handle multiple languages ensures that the search engine can accurately interpret queries and return relevant results, regardless of the language in which the music metadata is stored. Speed is another critical factor; the search engine should provide results quickly, minimizing latency and ensuring a smooth user experience. This is particularly important for large music libraries, where search operations can be computationally intensive.

Furthermore, the search engine must return all relevant results, ensuring that no potential matches are overlooked. This requires a sophisticated indexing and search algorithm that can effectively sift through the music library and identify tracks that match the user's query. However, simply returning all matches is not enough; the engine should also prioritize results based on relevance, presenting the most likely matches first. This prioritization enhances the user experience by reducing the time spent sifting through less relevant results. In addition to these functional requirements, the implementation of the search engine should adhere to several important qualities. It should minimize the use of dependencies, relying on stable and well-supported libraries whenever possible. This reduces the risk of compatibility issues and ensures long-term maintainability. The search engine should also be designed with a small memory footprint, especially for additional servers, to minimize resource consumption. Simplicity and ease of maintenance are also paramount, as a complex system can be difficult to troubleshoot and update. Finally, the implementation should have robust test coverage, with a minimum of 75% test coverage, to ensure reliability and prevent regressions.
