Field Searching

Field Search

The system offers the ability to search within specific metadata fields, for example the title, author or abstract field. A list of fields can be found in the advanced search dropdown menu. Field searches are conducted by typing the name of the field following a colon and the desired keyword(s), for example: author:Einstein. If multiple keywords are used within a field search, special syntaxes are required:

Search type

Syntax

Example

Expected Behaviour

Partial Phrase

"double quotes"

subject:"particle physics"

Keywords need to be in same metadata field, but will also return results for e.g subject:high energy particle physics. The order of the words matter.

Exact Phrase

[brackets]

subject:[particle physics]

Will only return results if metadata in specified field exactly matches the query.

Special characters: if a keyword includes special characters, syntax is required (such as parenthesis or quotes, e.g. author:"Saint-John"). The search engine uses the following special characters to designate syntax and thus should be avoided in simple searching: + - = & | > < ! ( ) { } [ ] ^ ~ * ? : \ /  

MARC Fields

The system also supports search within MARC fields. To search within a MARC field, simply use the same syntax as described in the above section. Please note:

Field

Syntax

MARC field

To search in the main MARC field, type for example 245:"Einstein Theory of Relativity"

Subfield

To search in a specific subfield, both indicators must be specified as well. For example: 24510a:"The Einstein Theory of Relativity"

Wildcards

Any indicator, any subfield: 245:"query" or 245%%%:"query"

Any indicators: 245%%a:"query" or 245%1%:"query"

Any subfield: 24510%:"query"

Wildcards
The first three digits of the MARC field have to be digits, and cannot be replaced by wildcards. Searches such as 2%%:"query" and 24%%%a:"query" are therefore not supported.
