Better search systems might combine multiple search methods, along with features like popularity, recency, user history, redundancy with prior search results, click rate data, etc. Q&A retrieval performance may be also be improved with techniques like [HyDE](https://arxiv.org/abs/2212.10496), in which questions are first transformed into hypothetical answers before being embedded. Similarly, GPT can also potentially improve search results by automatically transforming questions into sets of keywords or search terms."
