Special search keys

You have a number of special search keys with which you can search for a specific subject, publication or author.

> Search by people
> Search by year of publication
> Overview of special search keys

1.  Search by people

People are indexed according to their 'last name,initials' or by 'last name,first name' (without a space after the comma). For example: Johnson,A or Johnson,Alfred. If you type in a name without a comma followed by the initials or first name, all people with that surname will be displayed. However, if you type in a name with a comma followed by the initials or first name, only people with names identical to that typed in will be displayed. Naturally, you can use wildcards here as well.

2.  Search by year of publication

If you are searching for publications by a particular author and you wish to limit the search results to a specific year of publication, you can modify the search operation by using the following search keys. You can search by year of publication using the following operators (the search engine does not include serials in the search results):

  AND JVU 1980   published in 1980  
  AND JVU < 1980   published in or before 1980  
  AND JVU > 1980   published in or after 1980  
  AND JVU 1980-1984   published between 1980 and 1984, including 1980 and 1984
