A semantic science search engine is designed to understand the meaning of words and phrases in a query, and to use that understanding to provide relevant and accurate results. In the case of the query "Tropical cyclone or ISU Cyclone?", the search engine would be able to identify that "Tropical cyclone" and "ISU Cyclone" are two different concepts, and would provide results that are relevant to both.

For example, the search engine might provide results that include information about the different types of tropical cyclones, their formation, and their impact on coastal communities. It might also provide results that include information about the Iowa State University Cyclones, the university's athletic teams, and their history.

By understanding the meaning of the query, the search engine is able to provide results that are both relevant and accurate, and that meet the user's needs.
