General Notes on Searching

You can search De Gruyter Online using the Quick Search or the Advanced Search. If you are a registered user of the site, your search criteria can be saved so that you can re-run the search at a later date.

Search is case insensitive

This means searches do not take case (capitalization) into account.
pascal finds articles containing 'pascal' or 'Pascal'

Boolean Operators
Within the search fields, the Boolean Operators AND, OR, and NOT allow you to perform searches that specify logical relationships between terms. By default, i.e. if you do not use an operator, an AND-relationship between the terms you enter is established in the full text field.

Wildcards allow you to construct a query with approximate search terms. Use a question mark (?) in or at the end of a search term to represent any one character and use an asterisk (*) to represent zero or more characters. There is one limitation to the use of wildcards: You cannot use a wildcard in a phrase enclosed in quotation marks.

adeno* finds adenovirus, adenocarcinoma, adenohypophysis, adenosine, etc.
b?nd finds bond, bend, band, bind
*ism finds entries containing eg “modernism”, “realism” or “relativism”

To search for documents containing an exact phrase, enclose the phrase in quotation marks. Phrase searches will not treat AND, OR, and NOT as Boolean Operators and will not strip out stop words.

"computational linguistics" finds articles in which the two words appear as a phrase
computational linguistics finds articles that contain both words, apart or together

Stop words
Stop words are such words as articles, pronouns, and other frequently used terms that don't normally add value to a search. These words are stripped out of a search query if they are not part of an exact phrase.

Special characters / Umlauts
Feel free to use umlaut and „ß“, the system will search for both the term with umlaut and without.

The fastest way to find results is the Quick Search

A search box is available on all pages of De Gruyter Online in the upper right hand corner of the screen. Enter a word or phrase in the box provided. Selecting the search button or hitting the enter key performs a default search: the full text of all title information and content on DG Online is searched and the results are displayed by relevancy to the search criteria.

There are two possible search result lists:

  • "Documents" shows all articles, chapters and database entries relating to your search criteria.
  • "Publications” shows all publication titles refering to a search. In the list of publications you always see cover image for the products..

On top of the results list there is a toggle to switch between the two lists.

It is possible that there may be only documents available for your search, or only publications. In this case you will get a "no results found" message. Please try changing to the other view or refine your search.

You can use the available facets on the right hand side of your search results list to further narrow your results. You can also resort your list by various criteria, such as title, date, source and author.

Further search options are available with the Advanced Search

To open the Advanced Search, select the 'Advanced Search' link that is available on every page underneath the quick search box. The following search criteria are available:

  • Full text: the full text of all publication descriptions as well as all articles chapters and database entries are being searched.
