Boolean Operators and How To Use Them
Used primarily with keyword searches, search tools are used to refine search strategies. While their concepts remain constant across various applications and resources, some electronic databases don't support all of them or their symbols may be slightly different. To make the best use of powerful search strategies, it is essential to check the database's HELP files to make sure the tools are available and that the chosen symbols are entered correctly.
This narrows a search. Both search terms must be found somewhere in the record, though not necessarily in the same place, such as part of an author's name and part of a title. GALILEO's default operator between search terms is "and".
In the library catalog, try a keyword search of "jazz and blues" to see what records are retrieved.
This broadens a search. Either search term must be found somewhere in the record. This is especially helpful when searching synonyms or words with various forms. Most Internet search engines' default operator between search terms is "or"... a primary reason a search can retrieve so many irrelevant records.
In the library catalog, try a keyword search of "jazz or blues" to see what records are retrieved.
This narrows a search also. A record can be retrieved only if the first search term is present and the second search term is not present.
In the library catalog, try a keyword search of "jazz not blues" to see what records are retrieved.
Some database software works best for these strategies when you first do a search for each search term to get the "mapping" strategy in place. Following this, you can then use a combination of the search sets retrieved with your search operator(s) of choice to further delineate your search.
Search operators can also be used with Internet search engines. It is essential to check the HELP files of your search engine of choice as to what its specifics are concerning search operators: some require that the words be in all capital letters, some accept two and not the other, some require the combination "and not" for the "not" operator.
Most will honor the use of the plus " + " and minus " - " signs as shortcuts for the use of the words "and" and "not." Precede a required word or phrase in the search query with a " + " and a prohibited word or phrase with a " - " . The use of these symbols in combination within one search query is also acceptable.
