Type: One of 'completion', 'correction'. Completion is used to complete a partial queryword. Correction is used to correct a complete queryword. Both return a list of suggestions.
Search: Boolean to signify whether the word is a searchterm, or a generic word. Searchterms are corrected/completed using an index of words that appear in articles. Generic words are corrected/completed using a generic list of words.
