By using AND, OR, NOT you can limit a search.
a search that allows for and/or arguments
a search that allows logical relations between parts
a search with logical expressions
a computer search method based on the mathematician George Boule's "mathematics of logic". The method broadens or narrows a search by the addition of the words AND, OR and NOT to search terms. nesting – a computer search method that embeds a search within a search by the use of brackets, e.g. ((New York OR Boston (newspapers NOT weekly) ) AND (big dig). truncation – a computer search method that broadens a search by shortening a word with the use of an "*", e.g. employ* (employee, employer, employing, etc)
a search for an article or book using Boolean operators
A search process that connects search terms with operators such as AND, and OR to retrieve more or fewer results.
Also called "advanced search," uses the terms AND, OR, NOT and NEAR to establish more precise relationships between search terms than conventional searching methods do.
This is named after the 19 th century mathematician named George Boole, who developed methods of working with specific sets of data. It′s basically a method of searching for information in databases, using any given keywords and the operators and , or or not to specify the relationships between the search terms.
A search which includes inclusion or exclusion of the documents containing the words through the use of AND, OR and NOT.
Boolean operators let you define whether multiple search term are matched within a text block (usually a web page). A Boolean expression is constructed by joining terms together with the three special operators: AND, OR, and NOT.Some search forms allow searchers to indicate that all the terms in a query must be matched (AND) or that a match on any one of them is enough (OR). Others match pages on any of the terms (OR) and require the searcher to add a plus sign (+) to indicate that a term is required. Still others allow the Boolean terms themselves in the query text.
A search formed by joining simple terms with AND, OR and NOT for the purpose of limiting or qualifying the search. If you search information on making jam, and your search also brings back information on making jam tarts, the Boolean search 'making AND jam NOT tarts' can narrow your search focus.
A computer search method using Boolean operators AND, OR, or NOT to manipulate the sets of bibliographic records retrieved.
Returns results based on Boolean logic. Boolean searching is used by advanced searchers with specific information needs. Curriculum Repository Search supports the standard Boolean operators and syntax: And (and, &); Or (or, |).
Boolean search is a specialized search wherein you can use operators like AND, OR, NOT, XOR to find exactly what you want.
A method Website visitors use to narrow search engine results by using special search modifiers (such as AND, OR, NOT) to define the results they are seeking. Example: "house AND mortgage", "car OR automobile", "boat NOT yacht". Advanced or experienced users are most likely to use Boolean search techniques.
A formal way of searching for information in an archive or document, connecting search terms with “Boolean operators” such as AND, OR and NOT. This is similar to, but more formal than, search facilities often provided with search engines.
A special search for information on the web. It allows the inclusion or exclusion of materials based on commands such as 'and', 'not, and 'or'. Boolean search methods are covered in Module 1 of this tutorial.
Lets you combine two keywords or phrases. The symbols that connect are called Boolean operators. Some operators used in the VWC catalog are AND or, OR, NEAR and NOT or -. Go to boolean searching for a quick tutorial on how to use these operators.
A search method using logical delimiters to specify the search object (e.g., all scientists who were born before 1920 and were women who worked in either medicine or physics). Using "and" in a search restricts the possibilities (the object must satisfy both criteria); using or expands them (the object may satisfy either criteria).
A technique for finding documents that include or exclude data based on multiple criteria. By combining or restricting search keywords using Boolean operators and, or, and not, you can specify simple or complex formulas. Boolean searching provides a standard command interface for extracting matching data from a database.
means of combining search statements or sets using the logical operators "OR" to expand a search and "AND" to restrict a search to articles that contain two or more specified elements together.
A search allowing the inclusion or exclusion of documents containing certain words through the use of operators such as AND, NOT and OR.
A search formed by joining simple terms with AND, OR and NOT for the purpose of limiting or qualifying the search. If you want information about kite flying in Arizona and get information on air fares and cheque clearance along with kite flying in Michigan, the Boolean search "kite AND flying AND Arizona NOT flying NOT cheque" will constrain or limit the scope of your search.

A method of searching for information in databases that combines search terms with the operators AND, OR, NOT, and parentheses. See a fuller explanation in our file, What is Boolean Searching
A method for searching for information in databases. A Boolean search combines search terms with operators such as AND, OR, NOT, and parentheses. For example, “cat AND dog” searches for sources in which both “cat” and “dog” appear; “cat NOT dog” searches for sources in which “cat” appears and “dog” does not.
A search based on which search terms you use (AND, OR, NOT).
search request that uses Boolean operators AND, OR, and NOT in various combinations. For example, China AND Japan, tea OR coffee, California NOT Sacramento.
Boolean Searching refers to a method of searching for combinations of words and phrases, usually with a free text retrieval system. The usual boolean operators are: AND, OR and NOT.
A search that includes Boolean operators such as NOT and OR that act on the other search terms. For example, the Boolean operator NOT excludes the word the follows it from the search results.
Search queries that may involve the use of AND, OR, and NOT to improve results. For example, to find information on a specific type of dog you could search for "golden retriever AND dog."
a search in which Boolean operators (AND, OR, NOT) are used
A Boolean search involves searching with words like AND, OR, NOT. Using these words and other similar words can help you get more specific results. For example, if you're looking for info on pop music, enter pop AND music and you'll get a list of sites that include both those words, not just one of them.
A search on a computer database or search engine for keywords that best describe your topic using boolean operators such as AND, OR and NOT.
a search of an electronic database which uses "and", "or", or "not" to link words or phrases. Examples are "Russia AND religion", "dogs OR cats", "American music NOT jazz". For further information see the Research Tips section of this site. Go To
A search that limits your terms with AND, OR, or NOT. For example, you may type into a search box: knitting AND sweaters NOT scarves. So your results will be about knitting sweaters specifically, with no results about knitting scarves.
A search query using Boolean operators; apples and pears, apples not pears, apples or pears, are three different searches because of the Boolean operators. ( See above).
A search formed by joining simple terms with AND, OR and NOT for the purpose of limiting or qualifying the search. If you search information on salmon fishing in Alaska, and your search also brings back information on trout fishing and diving in Alaska, the Boolean search "salmon AND fishing AND Alaska NOT diving" can narrow your search focus.
