Search from a different angle
As we know from current studies and user data analyses of search engine providers, most users enter max. two terms to start their search. By using the Knowledge Map, it is no longer necessary to enter even a single search term – just by a few mouse clicks the user can targetedly and comprehensibly reach the desired search result.
Your corporate knowledge at a glance
