Sometimes your search results may include items that we do not have access to. This happens when the Limit to full text option is not selected.
When the multiple Advanced Search is used, Limit to full text/Full text online only boxes are not selected by default which means you would get books or articles that we do not have full text access.
If you would like to use multiple keywords, you could use the single field Advanced search which ensures full text results.
If you want more functionality, use the multiple field Advanced Search and make sure you select both boxes on Limit your results section otherwise, you will get the results that are not full text- the resources that we do not subscribe to.
