Ask HN: Anyone using Redis for full-text search?
I only learned this morning that that's a thing that Redis advertises as capable of. However, I cannot find many case studies to establish how viable/practical is using Redis for this use case. Choose Redis when: You need very fast search on a relatively small dataset. Your search patterns are simple and well-defined. You're already using Redis as your primary database. Low latency is critical. Choose Elasticsearch when: You have large amounts of text data. You need advanced search features and relevance tuning. Your data is semi-structured or unstructured. You need sophisticated analytics capabilities. Scalability is a primary concern What's a relatively small dataset? For someone that could be 1m records for others that could be 1bn records Below 10M documents for single node. Below 100M documents for clustered setup. Total data size (including indices) that can comfortably fit in available RAM.
