BOOLEAN SEARCH LOGIC TECHNIQUES PLUS

This is possible through Boolean operators such as AND, OR, and NOT, plus symbols like + (add) and - (subtract). Search for a specific word or phrase in the source. A Boolean search, in the context of a search engine, is a type of search where you can use special words or symbols to limit, widen, or define your search. Search for a specific word or phrase in the text. Boolean search is using specific logic using just 5 key operators to help you get more targeted results when you search. Search for a specific word or phrase in the title. (search for the word sleep within five words of the word anxiety) Search for specific words in a specific number of words in your phrase. (Search for the phrase sleep deprivation.) To use Boolean logic, put the terms/synonyms within a set of parentheses and combine them with OR. Thats why its important to have as many search terms as possible. They wont give us information about used SUVs because we didnt ask for it. (Search for the term academic and its synonyms.) Without quotation marks, the search engine may assume that the phrase is a list of separate query terms. With these databases, however, you will get exactly what you asked for. (Limits results to results other than Wikipedia.) They connect your search words together to either narrow or broaden your set of results. (Limits results to only those with bears and not the term Chicago.) Boolean operators form the basis of mathematical sets and database logic. (Search for content that contains scholarly OR academic.)

(Search for content that contains both vegetarianism and obesity.) An example of Boolean logic is the use of recipes AND potatoes to find recipes that contain potatoes. Google also has a few additional operators that work to refine results.īelow are common boolean operators that work when searching within Google and Google Scholar, as well as an example of each. Boolean logic is defined as the use of words and phrases such as and, or and not in search tools to get the most related results. Using these operators, you are able to focus your search on the results that will be most helpful. This logic still underpins all digital devices to this day, existing in almost every line of computer code. His legacy was Boolean logic, a theory of mathematics in which all variables are either true or false, or on or off. Boolean operators are words or symbols used as conjunctions to combine or exclude keywords in a search. Boolean search is based on the work of prominent British mathematician George Boole.
