Analyzing Real-Time User Queries in OpenSearch Service

I have set up an OpenSearch service in AWS to power the search functionality on my website. Now, I want to analyze real-time user queries to gain insights into the most popular search keywords and trends. How can I achieve this? Are there any specific tools or features within OpenSearch that I can use to capture and analyze user searched keywords in real-time? I want to make data-driven decisions to improve the user experience and optimize the search functionality on my website. Any guidance or best practices for real-time keyword analysis in OpenSearch would be highly appreciated. Thank you!
