Searching MASSOLIT will yield different results depending on where you are on the site.
For example, if you start a search from the homepage you will be presented courses from across our various subject collections. A search for "World War I" will return relevant courses from our history collection such as 'Germany in the First World War, 1914-1918', but it will also show courses from other collections such as 'Poetry of the First World War'.
If you want to narrow down your search, you can navigate to a specific subject collection (e.g. Government & Politics) and then search within this page. Courses can be further narrowed down using the various filters to the left of your search results.
