Pinterest has announced a new feature that will allow users to search items that they have pinned, rather than all pins. This will make it easier to find something you know you pinned. It's really a feature that should have been included from the beginning. Now it's hear:
When you type a word into the search bar -- like San Francisco, beaches, or BBQ -- you can filter results by clicking "Just my pins." We'll show you everything you've pinned with that keyword in the pin description. Be sure to add words in your descriptions that will help you find that pin again.
The feature is rolling out on the web and will eventually be brought to mobile. Pinterest says they are currently planning to bring it to mobile, but they have not announced a firm date for when it will appear.
