# Use the filtering system

There are two ways to use Visibrain's filtering system : \
\- Click on existing filters \
\- Manually [add your boolean filter](https://help.visibrain.com/~/revisions/Sg0jEnRI9hg61KE4OFRP/useful-documents/list-of-operators-to-add-filters)s

## Filter by Clicking

You can click on any element within your platform!

Simply click on the indicator of your choice (for example, a hashtag), and instantly all data in the Explore section will update to show posts from the Topic that contain the clicked hashtag. The filter thus created is added at the very top, and you can remove it with a single click, by clicking on the small gray cross.

You can add and combine filters as much as you like. This allows you to explore the data in a "funnel" (drill-down) manner, easily moving back and forth between different filters.

Posts, users, and articles can also be filtered by clicking on the small target icon at the top right :\ <img src="https://2444971194-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F7gsihb5HLG1gcRHm99nq%2Fuploads%2FiwhdPVufHWSkio8QhgpH%2FCleanShot%202022-12-07%20at%2014.31.29%402x.png?alt=media&#x26;token=bbf766c9-f08b-46d5-aaa2-02efc1080e1f" alt="" data-size="line">\
