Eureka (English version): Searches

To search Eureka, simply enter the query terms in the search box and press the "Enter" key or click on the "Magnifying Glass.

A simple search is based on the concept of a single search box, entering terms that act as keywords. 

There are two possible search options, which pop up as a menu when you start typing the first search term. They can also be selected from the menu on the right-hand side of the box:

  • Global Search: searches for library bibliographic resources, both physical and electronic (locates, for example, book chapters and articles with full text link).
  • UPO Library: searches titles in the physical library collection (without a link to the text), but also includes electronic monographs.
  • Olavide Institutional Repository (RIO): searches the scientific production of the university community deposited in RIO.

When you type the word or words you want to search for, the different search options are displayed. In addition to the auto-complete system, Eureka suggests relevant options for the terms you enter.

In an Advanced Search, you can refine your search more expertly, choosing the specific field(s) where you want to apply your search terms (title, author, subject, description…), specifying how they appear (contains, is (exact), starts with) with additional filters in terms of type of material, language, date, etc.


To access the advanced search form, you must click on "Advanced Search" next to the magnifying glass:



An advanced search allows you to:

  • Select between "Global Search, "UPO Library" and RIO
  • Select the search index (Title, Author, Subject, etc.)
  • Filter by type of document, date, type of material

Please note that...

Searches can be flexibly combined in the same or in different fields, using the operators AND or NOT. 

You can specify how they appear (contains, is (exact), starts with) and use additional filters in terms of type of material, language, date, etc.  


In the top menu in Eureka, there are several buttons that allow you to perform the following actions:



  • Library home website: links to the website of the UPO Library.
  • A-Z Databases: this takes you to the access page for all databases subscribed to and selected by the Library.
  • Library Guides: this takes you to the library's Guides and Tutorials site, where you can find thematic guides, resources, and services.
  • Journal search: where you can search by title or ISSN of the journal and browse periodicals by category.
  • Browse search: you can search by author, title, series, subject (Library of Congress) and catalogue number.
  • Document supply: request to borrow an original document or reproductions of part of publications, which are not in our library collection and are available at any national or foreign institution.

How to specify your searches…

More specific searches can be performed in the basic search box as follows:

You can search for an exact phrase using quotation marks, if you want it to search for an exact segment of text:


You can combine different search terms using Boolean operators, which you must type in uppercase:

  • AND: this operator searches for all the terms included. It does not need to be entered as, by default, all entered terms are combined with AND:
When the search combination includes parentheses, you do need to type the AND operator, for example:
  • OR: this operator is used to broaden the search by retrieving documents that contain one or the other term (you can also combine expressions, with or without quotation marks).
  • NOT: this operator excludes the term it precedes from the search results.

If you want to search for variants of the same word you can use wildcard characters:

  • Putting a question mark (?) in the middle of a word is used to retrieve any character in that position: for example, type civil?ation and you will get results that contain both civilization and civilisation .
  • An asterisk (*) in the middle or at the end of a word retrieves words with zero or more characters in that position: For example, psychol* retrieves psychological, psychologist, or psychology.
