Building a semantic search API in Go with Meilisearch

Full-text search is one of those features that looks simple until you have to ship it. Typos fail silently. Category filters conflict with relevance ranking. The database LIKE query that worked at 10,000 rows grinds to a halt at 100,000. This tutorial walks through building a real search API in Go using Fiber and Meilisearch, complete with filter support, typo tolerance configuration, and a MySQL LIKE fallback for resilience.

This is roughly the architecture running search across 1,600+ cybersecurity articles at AYI NEDJIMI Consultants.

Setup
