Océano's global search box is very useful to find general information from a great variety of information resources. Besides, it allows us to search in all Library's bibliographical resources at the same time, whether it be printed books or journals or electronic resources.
Nevertheless, we must keep in mind that Océano retrieves results from a great number of resources at the same time, so searches usually retrieve lots of results. Therefore, this type of search is recommended only at early stages of research or when searching for general information.
It allows us to select the field we want to search in and build complex queries by means of Boolean operators, an essential searching tool to effectively interrogate the catalog by stablishing relationships between keywords, in order to obtain the closest results to our information needs, either by expanding our sprectrum (for instance: irish OR celtic), or by reducing it (irish AND celtic; irish NOT celtic). Océano allows us to define our search by:
As in any simple search, advanced searches allow us to carry out a global search (Everything) or a limited search related to a certain type of resource (Catalog/ Articles and more/ Loyola Repository/ Ebsco).
We can also define our preferences by searching for “Any field” or more specific ones, to which we can apply a double filter by selecting the way they manifest in the document (contains / is (exact) / starts with ).
Finally, in order to provide the maximum accuracy, it will be possible to add as many lines as we want (+ Add a new line) by using Boolean operators (AND, OR, NOT). Be aware of the possibility of adding more filters at the right hand, related to the type of document, language and publication date.
