Using Operators in the Search Bar

You can specify your search by using operators to combine keywords in the search field. The Boolean operators AND, OR and NOT permit complex combinations of several search terms. In the following table, you will find an explanation of each of the functions and their commands, as well as an explanation of the truncation operation to extend a search for words of the same root:

OperatorShort Cut KeyFunction



retrieves records that contain both search terms



retrieves records that contain either one search term or the other



retrieves records that contain the search term entered before NOT, but do not contain the search term entered after NOT



when attached to a character string, retrieves all records containing words that contain that character string

Examples: How to Use Operators

Hercules Farnese

Returns all records that contain both Hercules and Farnese. Neither the order of the terms is taken into account, nor do both terms have to appear in combination.

“Hercules Farnese“

Returns all records containing exactly this phrase or exactly this combination of terms, also taking into account the order of the terms.

Aspertini AND sarcophagus

Returns all records containing both Aspertini and sarcophagus. The result is identical to the search "Aspertini sarcophagus" or Aspertini + sarcophagus.

Aspertini + sarcophagus

Returns all data sets in which both Aspertini and sarcophagus occur. The same results will appear with the input Aspertini sarcophagus. They would also appear with the input Aspertini AND sarcophagus.

“Zuccari Laocoon“ - Getty

Returns all records that contain the phrase "Zuccari Laocoon" but not the word Getty. The minus excludes all records that contain Getty even if they contain both Zuccari and Laocoon.

Apollo , Belvedere

Returns all records that contain either Apollo or Belvedere


Returns all records in which the character string Mari- appears, such as records with the words Maria, Mario, Marius, but also maritime, etc.
