- Introduced a new Indeed parsing strategy to support job extraction from Indeed, including advanced filtering options. - Updated job search parser to include Indeed in the site strategies, allowing for combined searches with other job sites. - Enhanced README documentation with detailed usage instructions for the Indeed parser, including examples for keyword and location filtering. - Improved logging for Indeed parsing to provide insights into job extraction processes and potential CAPTCHA handling.
