Start with search_func/main.go lines 188-233 and inspect the range over searchResult.Hits, especially the calls passing hit to c.JSON. Trace how those responses are written and check whether the analyzer finding affects the returned data. Done means the finding is understood and the response behavior is verified without introducing a range-variable pointer issue.
