Search query syntax:
Typically, a query is just one or more words, for example: contact information By This query will find pages on which both query words are found.
Logical operators allow you to build more complex queries, for example: contact information or phone number This query will find pages containing either the words & quot ; contact & quot; and `` information '', or the word `` phone ''.
contact information is not a phone number This query will find pages containing either the words & quot; contact & quot; and 'information', but the word 'phone' does not appear. You can use parentheses to build more complex queries.
and, &, +
Operator boolean & quot; and is implied, you can omit it: query "contact information" is completely equivalent to the request "contact and information ".
The boolean or operator allows you to search for products that contain at least one of the operands.
The boolean not operator restricts the search to pages that do not contain the word after the operator.
Parentheses specify the order of logical operators.
