Besides entering a query in the standard search bar, you can also use the advanced search screen. You can activate this screen by clicking on Advanced. The screen consists of three parts:
In this part you can specify search terms by entering them in the search fields. For every line you can select an index and give search terms. You can combine the lines with booleaan operators.
You can also specify if the results will be sorted on relevance or year of publication. It is also possible to specify the year of publication. For example: 1948-1980 for publications published between 1948 and 1980, 1976- for publications published between 1976 and now and 1978, 1980, 1983 for publication published in 1978, 1980 and 1983. Last in the general part is the choise of language.
In this part you can select or not select materials. In the upperright you select all or none.
In this part you can select databases in which you want to search. In the upperright you select all or none. By restricting the result with "search in own library" you will find only publications present at your own library without articles.
