You can search in more than one field at a time by entering values in multiple search criteria fields. Depending on which option was selected when the web part was configured, search terms will be joined with either the OR or the AND operator.
- With the OR operator, items will be displayed in the search results if they match any of the search terms.
- With the AND operator, items will be displayed in the search results only if they match all search terms.
Contact your SharePoint site administrator if you are not sure which option is configured for the web part.
