1. Distinction of characters

    a) Upper/lower case alphabetical characters: Not distinguished

    b) Full/half-width alphanumeric characters: Not distinguished


2. Search by multiple keywords

    a) AND: [ ] (a space)
        Use a space to separate keywords.

    b) OR: [|] (a pipe symbol)
        Use  "|" (pipe symbol) to separate keywords.
        A space is required before and after the operator.
        A space after the operator (“|") can be omitted.

    c) NOT: [!] (an exclamation mark), [NOT], [-] (a hyphen)
        Use "!" (half-width exclamation mark), "NOT", or "-" (hyphen) to separate keywords.
        A space is required before and after the operator.
        A space after the operator ("!” and "-") can be omitted.


3. Search for an exact word or phrase

Please use [“] (double quotation marks).

 - The operators within double quotation marks (AND, OR, NOT) lose the function and are treated as normal character strings.
