Looks nice, thanks for sharing. I do find the three pieces of configuration to be inconsistent however. The first two have you flip a switch _on_ to turn something _off_. "Turn Off Quick Directs" and "Turn Off Deep Searching" would probably be better as "Quick Directs" and "Deep Searching" where the toggle defaults to the "on" state. They look very similar to iOS controls so I think the users' understanding of on/off state is already there.

As for the third option "Strict Search On", "On" seems redundant at best and misleading at worst. Misleading because I'm not sure if the text is going to change when I toggle the switch. Meaning I don't know if this is a static label telling me what the setting is or a dynamic label telling me what the current state is.

In summary, I would make the button text more consistent and change their default states: [x] Quick Directs [x] Deep Searching [] Strict Search

As a side note, the controls are different on the main page vs the result pages. On the homepage they are switches while on the results pages they are check boxes.
