The and operator returns any combination of the terms' plurals, synonyms, or alternate spellings.
Example: The query flavor and aroma returns only results that contain plurals/synonyms/alternate spellings of both terms.
Entering terms in quotation marks to create a bound phrase narrows the term to include.
Example: The query "flavor" and "aroma" returns only results that contain the exact spelling (includes plurals) of both terms.
Entering terms in parentheses to create an expression expands the number of terms to include.
Example: The query ("flavor" or "aroma") and "turmeric" returns only results that contain flavor(s), aroma(s), or both and turmeric.
