![]() ![]() ("comprehensive claims" OR "land claims") AND (indian OR native OR "first nations" OR indigenous) It's also possible to search for multiple synonyms using round backets and the OR operator. As a basic rule – always use ( )’s to combine words linked together with OR. It looks for all records that contain either of these words, then finds which of these also contain the term "land claims". The brackets tell the computer that "Indian" and "Native" both represent the same concept. Think back to doing math equations in school – the brackets work the same way in a database. Using round brackets ( ) in a search statement tells the system the order in which to perform the search. To do this, enclose the terms connected with OR within parentheses. It is possible to perform complex Boolean searches in which more than one Boolean Operator is used. This should be done cautiously, because as well as deleting the unwanted items, such a search will also eliminate records that discuss both the relevant topic as well as the unrelated topic. If you are retrieving many records that are unrelated to your topic, try using the NOT operator to eliminate a word. NOT is used to exclude a particular word or combination of words from your search results. If you are retrieving too many records, try adding another search term with the Boolean Operator AND. This search query would return a much smaller set of records, and the items found would be more specific to your research question. If you are retrieving too few records, broaden your search by adding a synonym with the Boolean Operator OR.ĪND is used to join words or phrases when both (or all) the terms must appear in the items you retrieve. The OR operator is particularly useful when you are unsure of the words used to categorize your topic or if information on your topic is even available. OR is used to join synonymous or related terms, and instructs the search tool to retrieve any record that contains either (or both) of the terms, thus broadening your search results. The Boolean operator we would want to use to connect the terms in these two rows is AND.There are three common Boolean operators: AND, OR, NOT (it's best to capitalize Boolean operators because some search tools require it). We’ve placed his name in the first row as a Subject, and placed the book title in the second row. The example below shows how you might search for works about Orhan Pamuk’s novel, My Name is Red. These define how the terms on each row relate to one another. The first drop-down menu in that row lists three Boolean operators – AND, OR, and NOT. The second row in Advanced Search allows you to add more terms to your search. Just type out your search terms using the appropriate Booleans.Įxample: philosophy AND history AND mathematics Advanced Search with Booleansįeatures built into Advanced Search help you structure more complex Boolean searches. There are no prompts in Quick Search’s Simple interface to suggest you can use Booleans, but you can. In Quick Search, keyword search terms can be combined with Booleans that help you broaden or narrow your search, depending on which operator you use. 3.7 Boolean Operators Booleans: AND, OR, NOTīoolean operators are connecting words (AND, OR, and NOT) that link two or more keywords or phrases in your search. ![]()
