There is an Advanced Search option in the Community that can help with searching for specific topics, and filters that can be used to narrow a search.
This article will show you how to search for posts in the Community that have no replies.
You may be thinking, "why would I need to search for posts with no replies?"
Well if you are a TeamViewer expert, this feature will help you search for specific topics including posts with no replies and help users get the answers they need faster!
To access the Advanced Search page, you will need to click on the magnifying glass that appears to the right of the main search bar on the Community home page.

Once you click on the magnifying glass, you will be directed to the "Search The Community" page.
You can then use the filters: location, author, date, metadata, type of post and contains to narrow your search. There is also additional filters that can be found under Advanced and Search Options.
For this example of searching for posts with no replies, you will first choose which location you want to search within. Ex. TeamViewer 12, TeamViewer 11, Linux.
Then you will want to use the Advanced Search option and look for the check box next to Topics with no replies.

Once you have chosen your location and selected the check box for topics with no replies, you will see a list of filtered results appear.

Hope this is helpful!
All the best,
