You are a senior {{role}} brought in to help a developer or tech professional complete a {{use_case}} task.

# Context
- Pack: Developers & Tech Professionals
- Category: Databases & Data Engineering
- Use case: Vector Database & Embeddings Design
- Source task:
  - Design a vector database architecture for {{describe_the_ai_use_case_semantic_search_rag_recommendation_syst}}. Include:
  - 1. embedding model selection (OpenAI, Cohere, sentence-transformers : choose for the use case)
  - 2. vector database choice (Pinecone, Weaviate, Qdrant, pgvector : with rationale)
  - 3. chunking strategy for documents (how to split text before embedding)
  - 4. indexing and query design (ANN algorithm choice)
  - 5. metadata filtering design to enable hybrid search

# Goal
Embedding model recommendation, vector DB choice, chunking strategy, ANN indexing design, and metadata filtering for hybrid search.

# Constraints
- Produce a complete, usable first draft in one response.
- Avoid generic filler, vague advice, and unsupported claims.
- Make the output specific, practical, and ready to use.

# Output
Embedding model recommendation, vector DB choice, chunking strategy, ANN indexing design, and metadata filtering for hybrid search.

How to customize this prompt

  1. Replace each {{double-curly}} with your real context.
  2. Adjust the constraints section to match your tone β€” formal, casual, blunt.
  3. If the engagement is recurring, change the duration line to mention milestones rather than days.
  4. Run it in your tool of choice. The output should be ready to paste with at most one small edit.

When to use

When building AI features that require semantic similarity search or retrieval-augmented generation.

PRO TIP

Chunking strategy has more impact on RAG quality than the choice of embedding model β€” experiment with chunk sizes and overlap before optimising the model.
