There are several ways to filter the data in your collection.
Indeed, you can filter your data either by entity, by tag, or both at the same time.
To filter by entities, simply click on the dropdown menu for "Entities" and select the entities that interest you.
If you want to filter by a specific tag or multiple tags, you need to click on the button "More filters" and select the tags that interest you.
There you go, you now have the data filtered according to your wishes!
Bonus: you can also enhance your data filtering by going directly to the Axes or Posts that interest you (e.g.: Environment, Social, Energy, Mobility, etc.).
