When the checkbox is checked, the sponsor name in the study
must exactly match the sponsor name in the search. For example, if unchecked, a search for Merck
in the sponsor field will find Merck, Merck KGaA, Dupont Merck, and Merck Sharp & Dohme.
When checked, only Merck, with no other words in the name, will be found.
