====== Details of Conditional expression ====== Conditional expression† is specified with a character string: a hash (＃) at the head, and after that, search condition of the specified format follows. You may use conditional expressions only when you search materials in the libraries. ===== Description format of conditional expression ===== A conditional expression is described with a pair of a search item and a value. Two or more pairs are available for an expression. \\ A conditional expression is described with a determiner and an operator. ** Determiner .. Determiner is a character string that represents a search item. A simplified 2-letter string is also available. ** Operator .. Operator is a character string that specifies how to evaluate a condition with values or pairs of search items and values. Operator includes the following: and, or, not, near, followedby and parentheses. \\ The following table shows the meaning of operators and examples of specification. ^ Operator ^ Meaning ^ Example ^^ ^ ::: ^ ::: ^ Value ^ Interpretation ^ | and | Applies to all entries. | computer and network | Applies to both "computer" and "network". | | or | Applies to one or more of entries. | computer or network | Applies to either "computer" or "network". | | not | Applies to none of entries. | not computer | Does not apply to "computer". | | ::: | ::: | computer not network | Applies to "computer" but does not apply to "network". | | near | Two words appear close to each other (in random order). | The target match 'computer' and 'network' and there are 20 or fewer letters between those words. | | ::: | ::: | computer near(5,10) network | The target match 'computer' and 'network' and there are 5-10 letters between those words. | | followedby | Two words appear close to each other (in the specified order). | computer followedby network | 「The words 'computer' and 'network' appear in this order and there are 20 or fewer letters between those words. | | ::: | ::: | computer followedby(8) network | The words 'computer' and 'network' appear in this order and there are 8 or fewer letters between those words. | | ( ) | Expands the string in ( ) first. | information and (computer or network) | Applies to either "computer" or "network" and also applies to "information". | For the number of letters for near and followedby, an arbitrary number can be specified. (A,B) indicates 'letters between A and B' and (C) indicates 'C or fewer letters'. Specify the number after near or followedby. In that event, do not include any space character before the number. When you specify determiners and operators, you may use any of double-byte or single-byte characters and capital or small letters. <WRAP note>Suppliment</WRAP> <WRAP list> * When you specify a determiner, an operator, equator, equal sign, or hash as a value, delimit it with double quotation marks. </WRAP> ===== Search items and values ===== A conditional expression is specified in the format "Determiner=Value". For the equal sign, you may use either double-byte or single-byte character. For some search items, such as location, which are provided in the form of both values and codes, you may use either codes or character strings to specify values. Use operators to specify two or more values for one search item, such as "material located in either the reference room or the stockroom" or "material whose title contains volleyball but does not contain beach". ===== Combination of conditions ===== To describe two or more pairs of a search item and a value to specify a conditional expression, use operators. ===== Determiners ===== |< 100% >| ^ Determiner ^^ Items for condition ^ Note ^ ^ Standard ^ Abbr. ^ ::: ^ ::: ^ | KEYWORD4 | K4 | Keyword | The same applies to the input area of brief search. | | TITLE | TI | Title | | | AUTHOR1 | A1 | Author | | | SUBJECT | SU | Subject | | | PUBLISHER | PU | Publisher | | | YEAR | PD | Publication year | Hyphenate the start and end years*. | | JFGROUP | JF | Japanese/Foreign group | Specify code. | | LANGUAGE | LA | Language | Specify code. | | CLASS | CC | Classification | | | CALLNO | CA | Call mark | | | ISBN | SB | ISBN | | | ISSN | SS | ISSN | | | GSMD | GS | G/SMD | Specify code. | | NCID | NC | NCID | | | LOCATION | LO | Location | Specify code. | | ARRIVAL | AR | New arrivals | | | MATERIALID | MA | Material ID | | | ANNEX | AN | Select annex | Specify annex number. | | USER11 | U11 | Item A | Search by partial match. | | USER12 | U12 | Item B | Search by partial match. | | USER13 | U13 | Item C | Search by partial match. | | USER21 | U21 | Code A | Specify code. | | USER22 | U22 | Code B | Specify code. | | USER23 | U23 | Code C | Specify code. | | USER31 | U31 | Item A | Search by partial match. | | USER32 | U32 | Item B | Search by partial match. | | USER33 | U33 | Item C | Search by partial match. | | USER41 | U41 | Code A | Specify code. | | USER42 | U42 | Code B | Specify code. | | USER43 | U43 | Code C | Specify code. | | DGROUP | DG | Digitalization group | | | EJOURNAL | EJ | Electronic | | | EJAGENCY | EA | Provided by | Specify code. | (*) Publication year (start or end year) may be omitted.
