save and unsave on tumblr?

[Klj]

On the tumblr app, I'm not sure if it is on the desktop site or not, when you search something there's a "save" and "unsave" option, can anyone tell me what this means?

[Insert-Name-Here]

When u click "save" that means u r "bookmarking" that search so when another day when u want to search the same thing, it's already there.

See my pic? It says saved, and those are the searches that I saved! It's really useful!

Unsave is when u don't want to keep that search anymore.
