Table of Contents


Simple and advanced search carry out a federated search both in the journals database and the book catalog. If serials are found, they will be displayed first.

For most of your search queries simple search is the tool of your choice.

Unless otherwise noted, the following general rules apply to searches:

Rule Tip Examples
Restricted AND search All search terms are automatically combined with Boolean AND (resulting in intersection); other operators are not available. Search terms must be separated by spaces. AND is not required. alberts molecular biology
Order of search terms Order of search terms is unimportant. Smith John would find John Smith as well as Smith John. Smith John ⇔ John Smith
Upper and lower case Upper and lower case letters do not play any role. ALBERTS ⇔ alberts ⇔ Alberts
Automatic end truncation Automatic end truncation is applied to all search terms (in the sense of term*), i.e. the search string Smith finds Smith as well as Smithson. Truncation operators are not required unless wildcard characters are used in the middle or at the beginning of a word. j am chem soc
Wildcard characters @ is used as wildcard character for exactly one letter. Gr@y would find Gray or Grey.

* is used as wildcard character for 0 or more characters. Colo*r would find color or colour.

# is used as wildcard character for exactly one digit. ### would find all 3-digit numbers.
## nmr
Phrase search The order of the search strings may be accounted for or exact word search may be carried out by placing the search terms within quotation marks: "Smith John". "j phys chem"
Exact word match Add a = before the search string for exact word match: =John =electron

Fields: Series Author Title Author names, title keywords, year or volume number may be entered. The following database fields are searched: Author, title, series title, publication year, volume number,titles of periodicals and all their variants including short title, preceding title, succeeding title and CODEN. atkins physical chemistry 2006
Stop words The following stop words will be filtered from search: an, and, das, de, der, des, die, ein, eine, et, für, in, of, on, the, to, und. Hint: If you want to include a stop word in the query, place a = in front of it: =of .
Terms such as volumes, volume will be transformed to vol.
journal of the american chemical society ⇒ journal american chemical society
Supported search For known searches that result in too many or zero hits a message "Do you mean ..." will be displayed, which proposes a hint for quick access to the information wanted or an alternative database. science
Suggestions When you type a query, the system proposes suggestions that match your query. A suggestion can be selected using the mouse or the cursor keys and copied to the search bar.  
Sort order Default sort order for serials: by title ascending, for books: by publication year descending.

Comparison operators In general it makes sense to use the operator that is proposed by the system for the selected database field. The following comparison operators may be used:
  • begins with: all search strings are truncated as illustrated by string*. However, a truncation symbol is not required.
    Together with "begins with", other operators may be entered in the field:
    =word: The word must exactly match.
    ==field contents: the field contents must exactly match.
    Initial value: denote a range with ...
  • ends with: all search terms are left truncated as illustrated by *term. A truncation symbol needs not be added.
  • contains: all search terms are right as well as left truncated, as illustrated by *term*. Truncation symbols are not required.
  • >: greater than.
  • >=: greater than or equal to.
  • =: equal to.
  • <=: smaller than or equal to.
  • <: smaller than
  • !=: not equal to
