With this processing, you can search for materials using variant forms of kanji or older character forms. The supported normalization patterns are as follows:
- (1) Searching using kanji variant forms, old character forms, and modern forms
- (2) Searching using both full‑width and half‑width numbers and symbols
- (3) Searching using both full‑width and half‑width alphabetic characters, and both uppercase and lowercase letters
- (4) Searching using alphabetic characters with diacritical marks (e.g., Á)
- (5) Searching using both kanji numerals and Arabic numerals
- (6) Normalization of variations in symbols such as the middle dot (・) and brackets, and automatic splitting of keyword strings into individual words
1.2.4. Suggestion Function
When entering a search keyword on the Advanced Search screen, you can use the Suggestion Function.
The Suggestion Function automatically displays a list of candidate keywords based on the characters you have entered.
When you begin typing a word in the search box, a list of suggested keywords will appear.
If you click a suggested keyword, or select it using the cursor keys, the keyword will be inserted into the search box.
The Suggestion Function is also available in the search box on the Home Page.
1.2.5. Layered Search
In Advanced Search [Holdings], you can narrow down the search by selecting Fonds/Series from the hierarchy displayed on the left side of the screen (red frame).
The hierarchy displays the Fonds/Series in a structured, multi-level list. By default, only the following top-level Fonds are shown: “Administrative Records,” “Official Gazettes,” “Judicial Records,” “Corporate Records,” “Donated/Deposited Records,” and “Cabinet Library.”
As shown below, you can select a Fonds/Series by clicking the checkbox to the left of its name. To clear the selection, click the checkbox again.
Multiple Fonds/Series across different levels in the hierarchy may be selected at the same time.
The selected Fonds/Series will be displayed in the Fonds/Series field in Advanced Search [NAJ Holdings], as shown in the example below.
By clicking the plus (“＋”) button to the right of a Fonds/Series, a list of its lower-level Fonds/Series will be displayed, as shown below. To hide the list of lower-level Fonds/Series, click the minus (“−”) button.
If you click the title (link) of a Fonds/Series in the hierarchy, the catalog information of that Fonds/Series will be displayed. For details, see “2.1.1. Fonds/Series Details.”
To hide the Fonds/Series hierarchy, click the left arrow button (“◀”) located between the hierarchy and Advanced Search [Holdings] , as shown below. To show it again, click the right arrow button (“▶”) once more.
