Databases on De Gruyter Online

De Gruyter Online offers access to a number of databases on various topics. An overview of all available and planned databases can be found here. De Gruyter additionally offers a number of eBookPlus products: these are eBooks that work the same way as a database. The products have specific search critera which offer a sophisticated search through the content. The following describes the specific functionality of all databases and eBookPlus products on De Gruyter Online.

A complete list of all direct access URLs of databases can be found here:




Searching databases

The search functionality can be found on the left hand side of the database content page. When opening the database you will see the entry field for the Quick Search. Entering a term here will search this term in the whole content of the database.

For more specific searches an Advanced Search form is available. Clinking on ”More search options” opens the Advanced Search form. Three entry fields are available, each of them is preset with a search criterium. You can select a different search criterium from the list available for each entry field.

A description of the individual search criteria and possibilities for each database on De Gruyter Online is available in a specific PDF document linked into each database underneath the search form.



All search fields offer an autocomplete functionality the way it is known from search engines such as Google. As soon as you begin to enter your search term, the system will offer terms that match your entry. If the term you wanted to enter is among the terms offered, simply click on the term to paste it into the search field, then start your search. If the required term is not available in the index shown please change what you have entered accordingly.

Search terms can be entered individually or as a phrase. The wordwheel offers either individual terms or, in the case of phrase-indexed search fields, phrases. These are automatically entered in quotation marks when pasted into the search field from the index list. In a phrase-indexed search field you can also enter individual search terms. To do this, just type your search term into the field manually and ignore the terms offered by the autocomplete functionality. Then click on “Search” to start your search. Please note that hitting the “enter” key on your keyboard will automatically select the first entry from the index list. Therefore it is necessary that after manually entering the search term the you want to search, the button “Search” is clicked.



If you are unsure about the spelling of a search term, or want to broaden your search term for inflections of this term, you can enter the term with the help of a wildcard character. 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”


Combination of search terms

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.
If you enter search operators manually between terms in the search field, please write them in capital letters.
pascal OR fahrenheit

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


Special characters / Umlauts

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


Search is case insensitive

This means searches do not take case (capitalization) into account – but only if you enter your search terms in small letters. If you use capital letters in your search query, the search becomes case sensitive. Please not that your search results can differ from what you had expected in this case.

If your search does not return any results, make sure all search terms are spelled correctly, try different or fewer search terms or try more general search terms.


Search results

The result after a search is one or more entries from the searched database. Results will be displayed in a results list.
You can sort your results according to the specifics of the database. You also have the possibility to increase the number of results displayed on one page to 100.
If you want to view an entry, click on the title in the results list. If you have access rights to this entry, the entry will be shown in the entry view.

If you do not have the right to access this entry, you will get the following options:

  • Log on to De Gruyter Online with your personal access credentials, if you have purchased access with an individual accout, or if you have an access token that you want to redeem.
  • Buy access to this database entry via the webshop. You can also purchase access rights to the whole database through the webshop. If you want to do this, go back to the start page of the database and begin the purchase process from there.
