Need a way to dismiss the iOS keyboard on iphone.

When filtering, after searching to select a property, the keyboard covers the "apply" button and can't be dismissed. Ideally the keyboard would be dismissed after clicking "search".

This is also an issue in the the general document search screen. When searching for a document, the keyboard stays on screen and can't be dismissed - it's blocking view of half of the list of document, and blocking the taskbar in the bottom.
