Simple or advanced searching
Most databases and search engines have a simple search bar on their start page. In this search bar you can enter a single search term, but you can also combine search terms, for example: university AND leeuwarden
Usually there are also more advanced options. You will find these under advanced search.
With an advanced search you can formulate your search query much more precisely, combine terms or exclude terms. You can enter more search terms at once, in different search fields.
Example: Advanced search in the NHL Stenden Library catalogue
