You can choose between two different search modes in RelBib: “Simple Search” and “Advanced Search”.
Enter a term in the search field and leave the search category on “All Fields”. The system will then search for this term in all possible search fields. The drop-down menu allows you to narrow the search down to one specific category: title, author, call number (DDC), subject or ISBN / ISSN.
You may specify your results by means of the filter settings in the right column of the search result list according to the following criteria:
- time: year of publication
- medium: open access, mediatype, format
- classification: call number (DDC), RelBib classification
- content: topic, genre, era, region
- form: language, author, publisher
Some of the filters allow multiple selection.
You can start an “Advanced Search” if you click on the link underneath the search field. Compared to “Simple Search”, here it is possible to start a search in several fields at the same time and thus to render your search more precisely. The "Match" setting lets you specify how multiple search fields should be handled. For certain complex searches it might be more useful to operate with search groups.
In addition to that, in the advanced search mode you can narrow your search down a priori according to the following facets: RelBib classification; format; language. Moreover, it is possible beforehand to set a publication period as well as the number of results listed per page.
