Search Techniques This section will explain in more detail some of the ways you can search on Northern Light. Please visit the Optimize Your Search page for more search tips. You can use any of the search techniques described below alone or in combination with each other.Go: Optimize Your Search NATURAL LANGUAGE SEARCHING Northern Light is designed as a natural language search engine. You may enter your search in the same way you would ask a question or speak a word or phrase. Since you are not required to learn special search vocabulary or strategies, natural language searching represents the easiest way to find the information you need. Here are some examples of natural language searches: what is a good recipe for chicken risottoNorthern Light will look for all sites in our database which contain all of your search terms. Common words in the search, such as is, a, for, in, and the, will not affect the number of results returned for your search, but they will affect the relevance of those results. For more information on how relevance is determined by Northern Light, please see the General FAQ. BOOLEAN SEARCHING Boolean searching is a specialized search technique which relies on a system of logic developed by mathematician George Boole (1815-64). Boolean searching uses three expressions to determine results: AND, OR, and NOT. Using Boolean expressions, you can limit your results to very specific information. You may also use parentheses in Boolean searches to create complex Boolean expressions. Here are some examples of Boolean searches: Mozart OR Beethoven OTHER SYNTAX SUPPORTED BY NORTHERN LIGHT In addition to natural language and Boolean searching, Northern Light supports use of specific symbols within a search string to narrow your results according to specific criteria, or to expand your results to include multiple variants on a word root. Here are the symbols Northern Light supports, and some examples of their use:
FIELD SEARCHING Northern Light has classified our index into searchable fields. You can search these fields by adding the field delimiter followed by a colon [:] before your search term. Field delimiters can be used with any search form. Field searches may contain any of the above syntax including Boolean expressions, and may also be used within larger Boolean expressions. For a list of field delimiters supported by Northern Light, and examples of their usage, please see the Optimize Your Search page.
