Table of contents
Download Data
Load documents, build the VectorStoreIndex
Example: HyDE improves specific temporal queries
First, we query without transformation: The same query string is used for embedding lookup and also summarization.
Now, we use HyDEQueryTransform to generate a hypothetical document and use it for embedding lookup.
In this example, HyDE improves output quality significantly, by hallucinating accurately what Paul Graham did after RISD (see below), and thus improving the embedding quality, and final output.
Failure case 1: HyDE may mislead when query can be mis-interpreted without context.
Querying without transformation yields reasonable answer
Querying with HyDEQueryTransform results in nonsense
In this example, HyDE mis-interprets Bel without document context (see below), resulting in a completely unrelated embedding string and poor retrieval outcome.
Failure case 2: HyDE may bias open-ended queries
Querying without transformation yields a reasonable answer
Querying with HyDEQueryTransform results in a more biased output

Load documents, build the VectorStoreIndex
Example: HyDE improves specific temporal queries
First, we query without transformation: The same query string is used for embedding lookup and also summarization.
Now, we use HyDEQueryTransform to generate a hypothetical document and use it for embedding lookup.
In this example, HyDE improves output quality significantly, by hallucinating accurately what Paul Graham did after RISD (see below), and thus improving the embedding quality, and final output.
Failure case 1: HyDE may mislead when query can be mis-interpreted without context.
Querying without transformation yields reasonable answer
Querying with HyDEQueryTransform results in nonsense
In this example, HyDE mis-interprets Bel without document context (see below), resulting in a completely unrelated embedding string and poor retrieval outcome.
Failure case 2: HyDE may bias open-ended queries
Querying without transformation yields a reasonable answer
Querying with HyDEQueryTransform results in a more biased output
