BI’s Article search uses Boolean search capabilities. If you are not familiar with these principles, here are some quick tips.
To search specifically for more than one word, put the search term in quotation marks. For example, “workers compensation”. This will limit your search to that combination of words.
To search for a combination of terms, use quotations and the & symbol. For example, “hurricane” & “loss”.
The World Trade Organization's agreement on Trade-Related Aspects of Intellectual Property Rights established minimum levels of protection on issues that WTO signatories agree to observe.
