I have topics which has their sub-topics, and these sub-topics has their own set of sub-topics.
Eg. Appliances -> Large Appliances (sub-topic of Appliances) -> Refrigerators (sub-topic of Large Appliances).
Now when I search for refrigerators in search bar, I am presented with search result "Topic: Refrigerators" which is an expected behaviour. However on clicking it, I get an 404 Error.
