By adjusting this weight, you can control the influence of keyword similarity in relation to other similarity measures. The default value is `0.7`. - `top_n`: `int` This argument specifies the number of top chunks with similarity scores above the `similarity_threshold` that are fed to the LLM. The LLM will *only* access these 'top N' chunks. The default value is `8`. - `variables`: `list[dict[]]` This argument lists the variables to use in the 'System' field of **Chat Configurations**. Note that: - `knowledge` is a reserved variable, which represents the retrieved chunks. - All the variables in 'System' should be curly bracketed. - The default value is `[{"key": "knowledge", "optional": True}]`. - `rerank_model`: `str` If it is not specified, vector cosine similarity will be used; otherwise, reranking score will be used. Defaults to `""`. - `top_k`: `int` Refers to the process of reordering or selecting the top-k items from a list or set based on a specific ranking criterion. Default to 1024. - `empty_response`: `str` If nothing is retrieved in the dataset for the user's question, this will be used as the response. To allow the LLM to improvise when nothing is found, leave this blank. Defaults to `None`. - `opener`: `str` The opening greeting for the user. Defaults to `"Hi!
