While searching for things in Cosmos, it gets to know more about you, and therefore it gets better at predicting what you want by looking at past searches. This is done by taking into account:
- Actions you saved
- Actions you have favorites (clicked the star icon)
- Your most recent Actions used
- Actions not on the top of the list that you have clicked instead
By gathering this, Cosmos will try to display the most relevant search on the top of the list.
(No data is ever sent about your searches and can easily be reset under settings).
