IQS-GenericSearch

Performs a real-time web search using Alibaba Cloud Information Query Service (IQS) with time range filtering. Live web data improves the accuracy and timeliness of AI responses.

The output variable is an Array<Object> that contains the following fields: title(String), link(String), summary(String), content(String), markdown_text(String), score(Number), publish_time(Integer), host_logo(String), hostname(String), site_label(String), and scene_items(Array<Object>).

Input

• Search keywords: Keywords for the web search. Must be 2-100 characters. Strings longer than 100 are truncated; strings shorter than 2 return an error.

• Time range: Time frame for the search. Valid values: NoLimit, OneDay, OneWeek, OneMonth, and OneYear.

• IQS connection: Authentication depends on the instance RAM role. RAM role-based authentication is recommended for security.

  • Authenticate with a RAM role (Recommended)

    • Applicable when the instance RAM role is a custom role with the AliyunIQSFullAccess permission policy attached.

    • No IQS connection needed. The system authenticates automatically via the RAM role.

    • RAM role authentication stays within a VPC and does not traverse the public network.

  • Authenticate with an API key (Not Recommended)

    • Applicable when the instance RAM role is the default PAI role or a custom role without the required permissions.

    • Configure an IQS connection. Service Connection Configuration - Custom Connection. Set the key to api_key and get the value from the Information Query Service - Credential Management page.

    • API key authentication accesses the service over the public network, which is less secure.

Output

• output: Search results as a List[Dict] with the following keys:

  Key	Description
  title	Title of the result.
  link	URL of the result.
  summary	Summary of the result.
  content	Full content of the result.
