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.
