Hi all,
In other Knowledge solutions that I have used I have seen the possibility of adding a "golden word" (I can't remember the exact declaration of the function) to an article. For example, you might have a lot articles containing the word Iphone, but if someone searches for the word Iphone there is a specific "Iphone overview" article that should always be displayed as the first article, as this gives an immediate overview of what this phrase is about.
Do you have this function in Confluence?
