Currently, it is not possible to track analytics (eg. conversion rate, click through rate etc.) for queries that have redirect rules in place.
If a search returns 0 hits before the redirect, it will appear in Searches without Results in the Search Analytics. For queries that do return results, no clicks or conversions will be recorded because the redirect prevents user interaction with the original results.
If the redirect takes the user to a category page powered by Algolia, activity will be tracked. However, the analytics will be based on the category filter that is applied, rather than the original search term.
