Search recommendation redirect fix

[shashankdaima]

[NOTE]: After thorough testing via direct inspection of production API responses, it was observed that the search recommendation feature might encounter issues if parent.courses[0].courseId is chosen as the courseId in the URL. However, upon utilizing the maximum value of courseId, the redirection functions correctly. Hence, this PR addresses the concern.

PR Enhancements:

• Resolves an issue where the application crashes in certain Search Result scenarios, particularly those involving multiple parent.courses.

Fixes #478
