Keyword expressions allow you to construct your own complex queries in Advanced Search, letting you combine multiple keyword-based search terms that follow this basic syntax: search_field:phrase. For example, to search for all messages containing "Alert" or "Notification" anywhere in the Subject field.
Click the Basic > Search tab, and then click Advanced.
Select Email as the item type, and then select Keyword Expression as the parameter.
In the text field, type: subject:"Alert" OR "Notification".
Click Search to return all matching search results.

The phrase can only contain a single item. However, that one item can be any one of the following:
a single Text-based string;
a single Integer number-based string;
a single Wildcarded string;
a single Domain-based string (for to and from search_field only);
a single compound search string created by combining multiple strings with the keywords AND and OR, and grouping the phrases with parentheses to control the logic.
