Search system ignores singular and plural, upper case and lower case, articles and order of searched words: research is in fact stem based. All the searched words are linked in an AND research, both when in different fields or in the same field. You can also launch a "negative" search, prepending the minus (-) sign to the word or the words that you want exclude from the research.
If you don't want a stem based research, precise search is also available.
Results are shown as a list of short records, with facet filters available for further refining your research.
