+
+| Name | Description | Notes |
+|------|-------------|--------|
+| [**Full-text search**](full-text.md) | Traditional lexical search with analyzers and relevance tuning | Essential foundation for keyword matching, works out of the box |
+| [**Vector search**](vector.md) | Similarity search using numerical vectors | Requires extra setup/resources, ideal for finding similar documents |
+| [**Semantic search**](semantic-search.md) | Meaning-based search using natural language understanding | Requires ML models and vector infrastructure |
+| [**Hybrid search**](hybrid-search.md) | Combines lexical and vector/semantic approaches | Best balance for both keyword precision and semantic relevance |
+| [**Re-ranking**](ranking/semantic-reranking.md) | Post-processing results to improve relevance | Optional ML-based enhancement for fine-tuned relevance |

+ Full-text search is a very powerful tool in itself. One of the key strengths of {{es}} is its flexibility, allowing you to start with full-text search and gradually incorporate more complex or resource-intensive approaches over time.
