Improvements to search relevancy and seperation of search/autocomplete feature.

-- Removed `getSuggestion`

-- Added `getResults`
-- Added `getAutoComplete`

Restructured to search query to bool query that searches on a claims name, title, author and keywords in descripton -- `it's a disaster` now shows in a search for `disaster` autocomplete also returned correctly for the same example.
