How to deep search
You can narrow down your searches by searching for multiple levels of search terms at a time. We call it deep searching.
As a simple example, say you want to see only black cars you saved in your mind.
First, type “object: car” in the search field, which will show you all the images of cars.
Now add the second search term, "black."
Now say you want to see all black cars besides BMWs. You can exclude BMWs from the search by adding a minus sign “-” in front of that keyword.
You can deep search by date, color, object, category (such as notes, images or tweets) and more. Simply add your keyword or search term, hit enter and add the next one.
