The VIVO Search results include the names of the classes of the entity being displayed. So, for example, a person in a search result is identified as an Agent, an Independent Continuant, and other classes of little interest to the user of VIVO (this information is available on the "Edit this Individual" page for the ontologists who need it).
The search results can be improved by removing the list of classes names.
It appears that removing the class names can be achieved by removing a single line of code. https://github.com/vivo-project/Vitro/blob/1570f529571b924029b401fd918f43144e35afdf/api/src/main/java/edu/cornell/mannlib/vitro/webapp/searchindex/tasks/UpdateDocumentWorkUnit.java#L179
