You can use the following logic operators to control the search behavior:
Minus (–) operator
Use the minus (–) operator to exclude occurrences of the specified word. You can also use Advanced Search to exclude occurrences of specified words (see “Excluding unwanted terms,” Section 4.5.1).
Plus (+)/and operator
Use the plus (+) or “and” operator to indicate that the search must include the specified word. This operator is generally used in conjunction with the permute operator.
Permute (@N) operator
Use the permute operator (@ symbol followed by a number) to indicate how many intersections of the words listed in the search panel the search should locate.
