Added documentation

Fixed: Double results no longer returned

When searching for text associated with a shortcut, a window is no
longer returned twice for matching with both the shortcut text and the
actual search text

Fixed: Shortcuts don't occlude actual searches

- Searches that have been matched to a shortcut also return the actual
text results (eg. 'i' being a shortcut for 'internet'. we now return
results for both 'internet' AND 'i' instead of just 'internet')
