Top keywords and unanswered keywords reports contain the same keyword
The search analytics top keywords and unanswered keywords report both include the same keyword.
This can occur:
when the 'keyword' was previously unanswered, but content or search configuration changes now result in the keyword returning results.
if the 'keyword' is a popular query in your search, but has no matching search results.
if the 'keyword' is a popular (multi-word) query in your search, but only partial matches for the query exist within the search index.
There isn’t really any solution to this as it is expected behavior. However, altering the timeframe for the analytics you are viewing may remove some of the keywords from the unanswered keywords list if content/configuration changes now mean that they are considered as answered.
