Put multiple search terms, directly referring to each other, in quotation marks. This is especially useful, if both search terms occur quite often individually:
If you enter multiple terms, these all have to occur in the document, for a title to be found, i.e. the terms are automatically connected with the conjunction AND. The more terms you enter, the more specific is the search query and the lesser results will be found.
On the right hand of the results list you find various possibilities to narrow your results, i.e. a certain time period, subjects, types of publications, persons, etc.
Click on one or several of the displayed elements in order to be shown only results that match a specific criterion.
Delete either all your filters on top of the filter area or one single filter by clicking the checkbox in front of it.
Use the pulldown menu "All fields" beside the search field to select a certain search field for your search terms:
- Institutions [as publisher of a publication]
- ISBN / ISSN
- Published in ... [enter title keywords of a journal or series]
