What is the Quick Search?

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:
Titles shows all articles, chapters and database entries relating to your search criteria.
Chapters, Articles, Entries 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 filters on the left 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.

What is the Advanced Search

A key feature of our website is the Advanced Search. The Advanced Search will come in handy when you are looking for more specific items. Visit the advanced search page by selecting 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.
Title: searches all publication titles as well as titles of articles, chapters and database entries.
Author: searches all authors and editors of publications, articles, chapters and database entries (if available).
DOI: to directly access a publication or an article / chapter by its DOI.
Subject: to narrow the search with the subject of a publication.
Keywords: searches keywords for publications, articles / chapters (keywords are only available for parts of the content).
ISBN/ISSN: searches standard journal and book numbers (print and online ISSNs, print and eBook ISBNs). They may be entered with or without hyphens.
Language: to narrow the search to the language of the publication or content item.

Which search options can I use?

Search is case insensitive
This means searches do not take case (capitalization) into account.
Example:
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
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.

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

Phrases
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.

Examples:
"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.

How can I refine my search results?

In the left-hand menu of a search results list you will find further options to narrow your choices by using filters, like for example sub-subject, publisher or publication date; these will help you to refine your result lists down to a manageable number of products. The list of filters you selected and/or searched for is listed above or near the results list. You can clear filters used to refine the results list, either by removing one at-a time or using the “Clear All” option to remove all filters at once.

Can I search within my search results?

Yes, you can also search within your search results: Just add more search criteria to the existing ones by entering a word or phrase in the search box in the left hand menu of the search result list.

Can I change the sorting of search result lists?

Yes, there are more sort options besides "Relevance" which is used as a standard for search results, i.e.: You may sort results by A-Z / Z-A regarding titles and authors; Publication date, new to old / old to new.

How do I manage saved searches?

To revisit a saved search in "My DeGruyter" / "My Searches" you must be logged in when saving it. Otherwise it will only be saved for your current session and will be showing up if you click "My Searches" in the upper part of the website.

When searching for ISBNs or ISSNs do I have to enter them with or without hyphens?

It doesn't matter, they are matched without punctuation.

Where do I find the printed versions of your products?

Search (and browse) functions are focused on titles, articles, database entries, and book chapters, not on formats. So you will find a title or a document first and then, when you are looking at the title information in the results list, see at one simple glance in which formats it is available.
