English terms are automatically stemmed to include plural and singular forms, as well as common suffix and tense variations.
An asterisk may also be used to truncate any term from either the beginning or end of the word, or in the middle of the word to replace a character.
From the main search results page, adding a facet means the search result *must* include that facet to be included in the search results (a boolean AND search).
If you click on "Edit search" from an existing search, it will take you to the advanced search page. Adding a facet from the advanced search page means that it *may* include that facet (a boolean OR search).>
For example, if I wanted a work that was in the library on George Frideric Handel, but only in languages I'm familiar with, I could do a keywork search for "George Handel", then limit by the facet "In the Library", then click "Edit search" and select "English" and "German" from the facets and click Search. This will give search results in either German or English.
