The community name does is not getting displayed under any content type in search result page. For example: The search will only display if the search word is in a forum, wiki, file etc. It does not list specifically the Community name. This can reproduced in-house, on all browsers. It does not have any sort or filter option to quickly find content created by/shared with a user or created in a community. So if a user forgets the content name and is a part of multiple communities, they would need to go to the specific community to find the one they are looking for.
