FAQ

How can I combine multiple search criteria? (e.g., searching for items containing "○○" or "△△")

You can perform the following three types of searches (logical operations) by entering multiple search terms into a single search field or by entering terms into multiple search fields.

 

When entering multiple search terms into a single search field (Available in both Simple Search and Advanced Search screens)


AND Search

: Searches for materials that satisfy two or more search terms simultaneously.
How to enter: Connect each search term with a " " (space).
Example: To search for materials that contain both "Japan" and "America":
"Japan America"

OR Search

: Searches for materials that satisfy at least one of two or more search terms.
How to enter: Connect each search term with a "+" (plus sign).
Example: To search for materials that contain either "Japan" or "America":
"Japan+America"

NOT Search

: Searches for materials that satisfy a certain condition while excluding those that meet other conditions.
How to enter: Connect each search term with a "^" (caret sign).
Example: To search for materials that contain "Japan" but not "America":
"Japan^America"

 

When entering search terms into multiple search fields (Available in the Advanced Search screen)


AND Search

: Searches for materials that satisfy two or more search terms simultaneously.
How to enter: Enter search terms into multiple fields and select "AND" from the pull-down menu between the fields.
Example: To search for materials where the title contains "Japan" AND the author name contains "Tokyo":
Title: Japan
Pull-down menu: AND
Author Name: Tokyo

NOT Search

: Among materials that satisfy one condition, this excludes those that satisfy another condition.
How to enter: Enter search terms into multiple fields and select "NOT" from the pull-down menu between the fields.
Example: To search for materials where the title contains "Japan" but the author name does NOT contain "Tokyo":
Title: Japan
Pull-down menu: NOT
Author Name: Tokyo
