The advanced search feature is a powerful tool that allows you to increase the accuracy of the answers to your questions. You can switch to the advanced search mode by clicking on the "Advanced Search" switch button on the right panel in the "Q&A" section.
The advanced search feature is based on Hypothetical Document Embedding (HyDE), a precise zero-shot dense retrieval method. It can be used to retrieve documents that are relevant to a given query, even if the query is not present in the document. The advanced search has relatively lower response speed than the normal one.
