Frequently Asked Questions
Want to take advantage of the semantic search capability available at SciTech Connect? Select "Semantic" on the basic search form or in the advanced search "All fields" option. A semantic search technique called keyword-to-concept mapping is utilized, so your search term will be mapped to related scientific concepts allowing you to retrieve results related to your search term, but also to explore narrower and similar concepts. Boolean operators are ignored in the basic search so your term can be easily mapped to other concepts.
This technique is an expansion of your search and will generally return a larger number of results. This powerful and intuitive search can take several seconds to complete.
Using semantic search, a search for wind energy would be expanded to approximately 48 terms associated with wind and energy, including these:
Selecting the semantic search option applies only to the terms entered in the basic search keywords field, or in the advanced search "All fields" field. Other fields apply their supplied query terms directly, and allow boolean operators to be used.
- wind power
- renewable energy
- wind turbines
- energy efficiency
- energy conservation
- geothermal energy
Term search applies the provided search terms exactly as entered, with no concept mapping, and allows use of boolean operators. If you are searching for a very specific title, author, or keyword, the term search may be more appropriate.
