Learning from Bing Search

UFO can enhance the AppAgent by searching for information on Bing to obtain up-to-date knowledge for niche tasks or applications beyond the AppAgent's existing knowledge base.

Mechanism

When processing a request, the AppAgent:

  1. Constructs a Bing search query based on the request context
  2. Retrieves top-k search results from Bing
  3. Extracts relevant information from the search results
  4. Generates a plan informed by the retrieved information

This mechanism is particularly useful for: - Tasks requiring current information (e.g., latest software features, current events) - Applications or domains not covered by the agent's training data - Dynamic information that changes frequently

Configuration

To enable Bing search integration:

  1. Obtain Bing API Key: Get your API key from Microsoft Azure Bing Search API

  2. Configure Parameters: Set the following options in config.yaml:

Configuration Option Description Type Default
RAG_ONLINE_SEARCH Enable Bing search integration Boolean False
BING_API_KEY Bing Search API key String ""
RAG_ONLINE_SEARCH_TOPK Number of search results to retrieve Integer 5
RAG_ONLINE_RETRIEVED_TOPK Number of retrieved results to include in prompt Integer 5

For more details on RAG configuration, see the RAG Configuration Guide.
