Search tips

You can do a simple search by adding one or more terms. DiscoveryUPC will return you results that contain all the terms used. 

For best results use the different Boolean operators 


To find an exact phrase put the terms between "".

  • Examples: "Environmental pollution"



Boolean operators allow you to expand or narrow words or groups of words to get a more accurate search.

  • They must be written in English and in capital letters.
  • Multi-operator search is processed from left to right



  • In simple search if no Boolean operator is used it is interpreted that you want to retrieve all terms
  • You can add "AND" between terms but ranking will always apply better results if "AND" is not added


  • Use "NOT" to exclude a word or words from your search (chemistry NOT physics)


  • Use "OR" when you only want to retrieve one of the terms (chemistry OR physics)


It is recommended to use parentheses when more than one operator is used to set the search priority


This search retrieves information about Gaudí and the holy family or the Casa Batlló

  • Gaudi AND (Sagrada Familia OR casa Amatller)

If () is not specified in the previous search, DiscoveryUPC detects that it is wanted near Gaudi and sagrada family or house Amatller

  • (Gaudí AND Sagrada Familia) OR Amatller house


Wildcards allow you to expand your search


  • ?: the question mark is used to replace a single character. Indicating "europ?"you will recover" europa, Europeane, ..."


  • * : the asterisk allows you to retrieve the word string. Writing "industry*"recover" industryl", industryles industrialization, ..."


  • Use the filters on the left to limit results


  • Select "Include references without full text" if you can't find the information


  • Use advanced search


  • Save your searches in case you need to reproduce them later.
