Close keyboard after "Search" is tapped

[alanjosephwilliams]

Description

Currently, when searching, the user:

• taps the list view, to view the list and filter UI
• taps the search field, which opens the native keyboard
• Enters search terms, then taps the blue "Search" button
• The search is then conducted, but the keyboard does not close.
• The user then has to tap outside the keyboard area, or the "done" button to close.

We need to either close the keyboard upon hitting "Search" on this keyboard or bring up a different keyboard that has only one "complete" key.
