You either haven't yet defined your tagging system or you want a fresh start without looking for things that you have in mind. The goal of the "Review" section is to help you start from scratch.
Click on "Review", the graph on top shows the top Concepts generated based on your historical data. Concepts are grouped in clusters based on similarity. The table below replicates the graph.
By clicking on the big bubbles or clusters in the graph, you can zoom in and dive into more detail. In the table, you can do the same by clicking on the arrows on the left; the arrows will expand each Concept to help you drill down.
Navigate the graph or the table until you see a Concept that catches your attention. In the graph, if you click on that bubble, there is a panel on the left that will take you to the tickets/documents when you click on "see documents". (In the table, the idea is the same but you have to click on the number of comments). Afterwards, you'll be redirected to the Search section.
If the Concept is valid in the search section, you can click on "add to tag" and "new tag" or add it to an existing tag.
Repeat this process until you've added all of the relevant Concepts for the tag. You can filter the Review section on the top with the "documents with no tags" filter to focus on the Concepts that haven't been used.
You can click on a tag in the tag sidebar to see which exact tickets/documents are being tagged.
If there is a Concept that is not relevant at all, you may click "hide" to permanently delete it from your system to make your search easier.
*Keep in mind the Concepts you are navigating don’t represent complex logical rules, so, you may need to combine them to build relevant tags. Click here to read more.
