Key quotes
· 5 pulledWhy not just use Elasticsearch? or What about Algolia? Those are valid options, but they come with complexity.
Sometimes you just want something that works with your existing database, respects your current architecture, and gives you full control over how it works.
The concept is simple: tokenize everything, store it, then match tokens when searching.
