Input (grade 8): The first parameter is main search term, which will be treated as a literal string if multi-part (e.g. will be searched as the single string "Albert Einstein" not "Albert" and "Einstein" separately).
Output (grade 4): The first parameter is the main word to search. If it is two words, it will search both words together (e.g. will be searched as "Albert Einstein", not "Albert" and "Einstein").
