The not operator excludes any combination of the terms' plurals, synonyms, or alternate spellings.
Example: The query flavor not dye returns results that contain plurals/synonyms/alternate spellings of flavor but excludes those that contain plurals/synonyms/alternate spellings of both flavor and dye.
Entering terms in quotation marks to create a bound phrase narrows the term to exclude.
Example: The query "flavor" not "dye" returns results that contain flavor(s) but excludes those that contain both flavor(s) and dye(s).
Entering terms in parentheses to create an expression expands the number of terms to exclude.
Example: The query (turmeric or aroma) not (dye or flavor) returns results that contain plurals/synonyms/alternate spellings of turmeric or aroma, but excludes those that also contain plurals/synonyms/alternate spellings of dye or flavor.
