Expert Search

A search box is provided in the section "Books & more" which allows you to perform an expert search by entering exact search terms together with the field names.

The search will run as a free text search if no field names are included.

A detailed list of filed names can be found below.

Search terms which consist of more than one word should be enclosed in quotation marks to prevent the second and additional words from being searched for separately in the free text search.

ti:Schwäbische Heimat => Search for 'Schwäbische' in the title field and 'Heimat' in the free text field

ti:(Schwäbische Heimat) => Search for both "Schwäbisch" and "Heimat" in the title field in any order

ti:"Schwäbische Heimat" => Search for the search terms in the given order (phrase)

Escape sequenz

The catalogue makes use of certain special characters in its search syntax.
These special characters must be entered into the search fields in a certain way so that they will be recognised as a search term.
To do this, enter a backslash before the special character.

This escape sequence is required for the following special characters:

+ - & || ! ( ) { } [ ] ^ " ˜ * ? : /

For example, when performing an expert search using the search term class mark (German=Signatur) the escape sequence is required.

The class mark 43 A 6611-1 requires a backslash to be added before the last "1". The blanks can be left out.

The correct search term would be:
si:43A6611\-1

Truncation of search terms is also possible in the expert search. A search term can be truncated on the right with the * character. Left truncation is not possible.

Example: au:(goeth*)

Truncation with * in the middle of the word is also possible. The asterisk stands for any number of characters. Often this form can be helpful with different spellings or languages. However, it often delivers unexpectedly many hits.

Example for the search of Toskana oder Toscana: ti:(tos*ana)

If only one letter is to be truncated, the search with the question mark ? usually leads to a more precise result than a truncation in the middle of the word:

Example: ti:(tos?ana)
Example: au:(ma?er AND w*) AND ti:psychiatrie

In expert mode, the following field names are searchable at "Books & more":

(*) = these aspects can only be searched in expert mode; input fields exist for the others.

Another special feature of the Expert Search is the possibility of using Boolean operators. With these operators you can make logical links between two or more search terms. In this way, you can, for example, narrow or broaden your search query.

AND, OR and NOT are available as operators. Note the capitalization!

Several entered search terms are automatically connected with AND. However, you must use the AND operator if terms are truncated or if a field label is used.

• AND
  A AND B means that the search term A and at the same time the search term B must be contained in each searched title. This means that you limit the number of hits.
  The more terms you link with AND, the smaller the number of hits.
  Example: ti:(naturpark AND schönbuch)
   
• OR
  A OR B means that each searched title must contain either the search term A or the search term B or both search terms. The more terms you link with OR, the larger the hit list will be.
  A search with OR is useful when searching with synonyms or with a search term in different languages.
  Example: ti:(lexikon OR lexicon)
   
• NOT
  A NOT B means that every title searched for must contain the search term A, but not the search term B. With this operator you limit your hit list.
  Example: ti:(astro* NOT astrolo*)
  For example, this query returns hits for both Astronomy, Astronomie and Astrophysics, but not Astrology or Astrologie.
