In a situation like this (where you aren't looking for a particular case, just a type of case), it may be best to use open web resources or the search box on the library home page to start your search. This will help you find articles or web sites that mention cases of interest that you could then find out more about in our legal databases.
To begin, you can use a web search engine (Google, Yahoo, etc.) to search for the phrase “legal cases” (in quotes to force it to find that phrase) along with a keyword related to the topic, for example:
You can also use the library home page. In the search box under the "Everything” tab, enter searches like the ones listed above.
After you've found a case that interests you, you can then use a legal database such as Nexis Unito search for the actual case by party (see directions here).
