HyDE Semantic Retrieval FAQs

Question 1

Can this skill handle multi-part queries?

Accepted Answer

Yes, the skill includes a 'Per-Concept HyDE' pattern that can decompose a complex query into multiple concepts and generate hypothetical embeddings for each in parallel.

Question 2

Which LLM models are recommended for HyDE generation?

Accepted Answer

For the best balance of speed and cost, small but capable models like Claude 3.5 Haiku or GPT-4o-mini are ideal for generating the hypothetical response.

Question 3

Does this skill increase search latency?

Accepted Answer

Because HyDE requires an initial LLM call to generate the hypothetical document, it can add 1-2 seconds of latency. This skill mitigates this using aggressive caching and a fallback mechanism that reverts to standard embedding if a timeout occurs.

Question 4

When should I avoid using HyDE?

Accepted Answer

HyDE is less effective for exact keyword searches, specific code snippet lookups, or when the query is extremely simple. It shines most in conceptual or natural language queries where the terminology might vary.

Question 5

What is HyDE and how does it improve retrieval?

Accepted Answer

HyDE stands for Hypothetical Document Embeddings. It works by using an LLM to generate a 'fake' answer to a query, then using that answer's embedding to search your database. This aligns the search vector more closely with the actual document content than a short query would.
