Semantic Search vs. Full-Text Search: Which Do I Choose in Milvus 2.5?

What this post added

This post introduces and demonstrates the integration of full-text search (FTS) with Milvus's existing semantic and sparse vector search capabilities in version 2.5. It details how hybrid search, combining BM25-based FTS with dense embedding semantic search and ranked by RRF, improves relevance. The post provides a case study using code snippets, analyzing query results and presenting performance metrics (Pass@5) to show the benefits of hybrid search over semantic search alone, and discusses the impact of stopword filtering.
