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
