Ability to enhance search results by creating keyword associations.
Example: Someone could be providing feedback on the "widget" but the word they use is "pop-up".
This would be especially helpful for companies that have custom names for functionality that may not be obvious to their users.
You have an article with the title "Show current tasks."
User searches "Show existing tasks."
Right now search would not match current to existing, even though they are synonyms. This requires the admin to add multiple keywords to the article title and body.
It would be helpful and ensure users found all matching articles if the search feature found synonyms of words in the search phrase.
