Search Facility Matching

[rnc]

This issue was spawned from the discussion on #80.

Currently the search facility is also case insensitive but is also using a fuzzy matching algorithm which means searching for e.g. RCM will return
Update RCM
and
Handle releasing in config and new document

The latter is a bit unintuitive. Would either an explicit regexp or ability to quote would be useful? Or restrict the 'fuz' distance? (if feasible).

@Thor77 mentioned "We should extract this functionality into an own function then to provide a consistent experience throughout the application."

@rnc I'm all for adding a --literal or --regex flag for search, would either of those work for you?
