What should I do if I want to use a combination of multiple search conditions (such as one including x or y)?

You can perform the following three searches by entering multiple conditions in a single search field or filling in multiple search fields (logical operation).


Entering multiple search values in one search field (enabled on the basic search screen and advanced search screen)


Logical AND search: Search for materials that simultaneously satisfy two or more search valuesEntry method: Connect all search values with " " (blank).Example: Search for materials containing both "Japan" and "America""Japan America"Logical OR search: Search for materials that satisfy any one of two or more search valuesEntry method: Connect all search values with "+" (plus sign).Example: Search for materials containing either "Japan" or "America""Japan+America"Logical NOT search: Search for materials that satisfy certain conditions and do not satisfy other corresponding conditionsEntry method: Connect all search values with "^" (caret).Example: Search for materials containing "Japan" but not "America""Japan^America"


Entering multiple search values in multiple search fields (enabled on the advanced search screen)


Logical AND search: Search for materials that simultaneously satisfy two or more search valuesEntry method: Enter search values in multiple fields, and select "AND" from the pull-down menu between the fields.Example: Search for materials containing "Japan" in the title and "Tokyo" in the author's nameTitle: Japan
Pull-down menu: ANDAuthor: TokyoLogical NOT search: Search for materials that satisfy certain items and do not satisfy other itemsEntry method: Enter search values in multiple fields, and select "NOT" from the pull-down menu between the fields.Example: Search for materials that contain "Japan" in the title and do not contain "Tokyo" in the author's nameTitle: Japan
