Get to know the Library's search engine

Search Tips

Choose any of these options from the search engine's drop-down menu:

The search box

  • All: all the contents available in the UOC Library, the O2 Repository and the recommended reading of the courses. 
  • Recommended reading: just the resources recommended by the University's teaching staff for further information on the courses.
  • Learning resources: search among the materials prepared by the UOC and used in the classrooms. 
  • The O2 repository: consult contents prepared by the UOC community and available with open access. This may be, for example, final projects or scientific articles.
  • Catalan University Union Catalogue: broaden your search with the contents available in other Catalan university libraries. You can request books on loan or digital articles.
Where to search


Using the button Extend the search beyond the UOC you will be shown books from other institutions which you can request on inter-library loan and digital articles which you can request from the Library.

The filters will help you hone your searches. The main filters are:

  • Availability: choose the type of document which interests you according to the format (online or physical copy), whether it is open access or the quality (whether it is peer-reviewed).
  • Type of resource: choose the type of documents, books, articles, theses or videos.
  • Journal title: thanks to this filter you will see the articles from the publications which have the term searched for in the title.
  • UOC collection: Special series of content grouped by the UOC.
  • Subject: get results for a specific discipline. 

To further finetune the results, you can select other filters such as the date or language.


The Advanced Search tool is integrated into the search box. The button only appears on the results page after you have performed an initial search on the Library website.

As the first step, start a session in the search engine with your campus username and password to see all its features.

Here are some tips to improve your searches:

  • The asterisk (*) is a wildcard. If you use it next to the root of a word, you will recover results that include all its variations.

Entering cultur* will retrieve content with the terms culture, cultural and culturally.

If you enter subject: librar*, you will recover all the documents that contain library, libraries or librarians as subjects.

  • If you add * or a question mark (?), you will replace a single letter of the word.

Entering wom?n will retrieve content for women in plural and woman in singular. 

  • The operators AND, NO and OR allow you to combine search terms.

If you search for college OR university, you will retrieve information that contains one or both terms. 

  • Adding quotation marks (" ") at the beginning and end of a phrase retrieves results for exactly those words.

If you search for "borderline personality disorder", you will see only documents that contain this exact phrase.

If you enter “history teaching” in the search box, you will obtain results such as Teaching History.

The operators AND, OR and NOT (they must be written in capital letters) help you refine your results in the Library resources search engine. You can use these operators to combine the search terms and establish relationships between them.
How can I use them? How can I refine my results even more? Combine the Boolean operators as often as you want to create personalized search formulas.

As in mathematics, you can use brackets to define the order in which the terms must be interpreted: the search engine reads first the words in brackets. For example, if you write your search as (children OR adolescents) AND learning, the search engine will first interpret that you only want information about children or adolescents and will then relate these results with learning.

Furthermore, if you want to search for results that contain a specific phrase, you can use inverted commas. For example: If you write "Olympic games", you will get results with the words "Olympic Games" in that order and together.
