How-To Guides
How-to guides are task-oriented recipes that help you accomplish specific goals. Each guide focuses on solving a particular problem and can be completed independently.
🤖 LLM Extensions
- Cache LLM Responses — semantic caching to reduce costs and latency
- Use LangCache as the LLM cache — managed cache service with LangCache
- Manage LLM Message History — persistent chat history with relevancy retrieval
- Route Queries with SemanticRouter — classify intents and route queries
🔍 Querying
- Query and Filter Data — combine tag, numeric, geo, and text filters
- Use Advanced Query Types — hybrid, multi-vector, range, and text queries
- Write SQL Queries for Redis — translate SQL to Redis query syntax
🧮 Embeddings
- Create Embeddings with Vectorizers — OpenAI, Cohere, HuggingFace, and more
- Cache Embeddings — reduce costs by caching embedding vectors
⚡ Optimization
- Rerank Search Results — improve relevance with cross-encoders and rerankers
- Optimize Indexes with SVS-VAMANA — graph-based vector search with compression
💾 Storage
- Choose a Storage Type — Hash vs JSON formats and nested data
💻 CLI Operations
- Manage Indices with the CLI — create, inspect, and delete indices from your terminal
- Run RedisVL MCP — expose an existing Redis index to MCP clients
