What are Elasticsearch and Pagefind?
Elasticsearch
Elasticsearch is a distributed, RESTful search and analytics engine capable of addressing a wide variety of use cases. It stores and indexes large volumes of data for fast full-text and structured search.
- Distributed full-text search
- Aggregations and analytics
- Horizontal scalability
- Rich query DSL
Pagefind
Pagefind is a fully static search library that indexes a built website and serves search entirely from the browser without a backend. It is designed to be low-bandwidth and easy to add to any static site.
- Browser-side search index
- No backend required
- Low bandwidth
- Multilingual support
