Why I can't find the same result at my frontend but can locate it at the backend of Algolia?

My website is chemwhat.com. When I search a result at the backend>indices of Algolia, I can find the result but can’t locate the same result at my website’s frontend. Suppose I search “85590-00-7”, I can find the result under Indices>wp_searchable_posts. However, I do not understand why I can’t get this result when still searching “85590-00-7” in my frontend chemwhat.com1
