Search by Keywords

About Search Page

This page will explain how to use Search All.

A. Search Data by Title, Author, etc.

A-1. Simple Search

Simple search finds data in which the character string entered in the free word input field matches somewhere in the various information (title, author name, etc.) of the registered data.

●Free Word Input Field

・You can enter multiple free words separated by blank characters (half-width / full-width spaces). In this case, it will be an AND search.
・For logical operations, refer to "A-4. Complex Search Methods".
・If numerical characters are used as free words, they can be either full-width or half-width characters.

  • Search Example
    To search for items including "Information Processing", "Digital Library Project", and "Jun Adachi", enter the following and click the search button.

A-2. Advanced Search

You can narrow down the search by specifying in detail which item to specify the term for, the relationship between multiple search conditions (logical calculation), the time of publication, and so on. Click "Advanced Search" to show / hide. AND search is performed between items.

  • Search Example
    When searching for items that include "information" in the title and "Jun Adachi" in the author or representative name.

A-3. Data Source Selection

If you want to limit the data sources, you can narrow down the search by checking the check box of the data source.

  • Search Example
    When searching only for "Information" in the title and limiting the data source to "IRDB."

A-4. Complex Search Method

  • If you want to search with a character string that includes space characters, enclose the character string with "" (double quotation marks). This is applicable only to single-byte characters such as alphabets and numbers. Example: "liquid crystal" → "nematic liquid crystal" or "liquid crystal polymer" return, but "crystal in liquid" or "liquid or crystal" do not.
  • To search by prefix, add "* (asterisk)" at the end of the character string. This is applicable only to single-byte characters such as alphabets and numbers. Example: work* → "worker" and "working" return, but "homework" does not.
  • Boolean Searches
    • You can perform Boolean search (AND, OR, NOT) as shown below. Double-byte characters can be used as the operator.
    • AND Search・・・・And Search finds terms that include all the keywords entered. Specify with space characters (half- or full-width), excluding code or ID fields, such as "_AND_" ( _ = a space character), or "_&_".
      Example: Searching on "information processing digital", "information processing AND digital" or "information processing & digital" returns terms that include both "information processing" and "digital."
    • OR Search・・・・OR Search finds terms that include any of all the keywords entered. Specify with space characters as in "_OR_" (OR in uppercase), or "_|_".
      Example: Searching on "information processing OR digital" or "information processing | digital" returns terms that include either "information processing" or "digital," or both.
    • NOT Search・・・・NOT Search eliminates terms that contain the specified term. Separate with "_NOT_" (NOT in uppercase). Alternatively, add a (half-width) hyphen immediately before the term to be excluded.
      Example: Searching on "information processing NOT digital" or "information processing-digital" returns "information processing" excluding "digital."
    • Priority of Boolean Search using parentheses・・・・You can specify the priority of logical operations by parentheses.
      Example 1: "Adachi NOT (Takeda AND Aizawa)" returns records that include "Adachi" but does not return those including "Takeda" and "Aizawa." "Adachi Takeda" and "Adachi Aizawa" return but "Adachi Takeda Aizawa" does not.
      Example 2: "(Adachi NOT Takeda) AND Aizawa" returns records that include "Adachi" but not "Takeda" and those that include "Aizawa." "Adachi Aizawa" returns, but "Adachi Takeda" and "Takeda Aizawa" do not.
