Hey @minxomat,
HyDE sounds like an interesting approach. All dense retrieval approaches suffer from the problem you outlined in the blogpost. Have you looked at keyword-based or late-interaction models for retrieval such as ColBERTv2[1]? I find that late-interaction methods seem to offer best trade-off between semantic intelligence (precision) and retriving relevant documents (recall).
