When searching for names of individuals, the safest strategy is to use their first initial and last name. However, in some cases this will yield unwanted results as the last name and first initial may be for different contributors to a publication or from different fields of an identity. For this reason, the most precise way to search for names of individuals is to enclose their last name and first initial within quotation marks (e.g., "Einstein, A"). However, should you use quotation marks, the order of your search terms becomes a factor and, thus, you must put the last name before the initial as this is how names are stored within the database.

Examples
CO(A EINSTEIN)
This would return results having EINSTEIN and A in any of the contributors' names. So although it would return results by Albert Einstein, it would also return results co-authored by Charles Einstein and Mary Ann Harbert.

CO("EINSTEIN A")
This would return results with a contributor names EINSTEIN whose first name begins with A. So in addition to results by Albert Einstein, it would also return results by Alfred Einstein.

CO("EINSTEIN A" NOT ALFRED)
This would return results with a contributor named EINSTEIN whose first name begins with A but would omit those with a contributor named ALFRED.

CO("EINSTEIN A" NOT "EINSTEIN ALFRED")
This would return results with a contributor named EINSTEIN whose first name begins with A but would omit those by ALFRED EINSTEIN (without omitting any other ALFREDs).

CO(EINSTEIN AND BORN)
This would return results having contributors named EINSTEIN and BORN.

CO(EINSTEIN AND BORN)
This would return results having contributors named EINSTEIN or contributors named BORN.
