All Meilisearch trails
  1. How Samtec modernizes product search with MeilisearchThis post details Samtec's migration from a previous search vendor to Meilisearch for their product catalog search. The migration involved two phases: first, content search (web pages, PDFs, videos), and second, product search with advanced filtering and faceting. Key technical challenges addressed included improving search relevancy for highly specific components, normalizing inconsistent product descriptions, reducing latency, and gaining granular control over ranking. The implementation leveraged Meilisearch's developer-first experience, instant performance, built-in relevancy features (typo tolerance, customizable ranking), and direct support. The outcome includes processing 1.5 million monthly searches and over 1 million indexed documents across four regional instances with near-instant response times, improved relevancy and speed, and better cost efficiency.
  2. Designing effective typeahead search for faster, smarter UXThis post provides a practical guide to building a typeahead search system using Meilisearch and FastAPI. It details the steps involved, including setting up Meilisearch, defining data samples, creating a search index, configuring searchable attributes, setting up ranking rules (including custom ranking by popularity), enabling typo tolerance with character-based settings, adding documents, and initializing the search index on application startup. It also covers building the search endpoint with speed and highlighting in mind, and creating a basic HTML/JavaScript user interface that debounces input and renders results. The post demonstrates the system's effectiveness with examples of movie search, highlighting speed and typo tolerance.
