![]() Most job boards will recognize the asterisk, but not all search engines do.Īdmin* = administration, administrator, administer, administered, etc. The asterisk is a time-saver so you don't have to write out long, complicated search terms. The autocomplete operator: Not exactly a search operator, but acts as a wildcard for Google Autocomplete. Boolean operators are a versatile and valuable tool for anyone using search engines to look for information online. The asterisk can be used for a root word, stem, or truncation. The operator source: This Google search operator source: works in a similar way as the site: operator, but only can be applied for newspapers that appear on Google News. The example given returns results that contain both software engineer and software architect. The keyword(s) within the parenthesis will be given priority. And combines search terms so that each search result contains all of the terms. ![]() You can use these operators to create a very broad or very narrow search. Parenthesis can be used to combine other Operators for a more complex search. The Boolean search operators are and, or and not. This is because Google Scholar offers limited options to combine multiple search terms with Boolean operators (like AND, OR, NOT). Boolean operators OR, Starbucks OR Costa, OR means you are searching for documents that contain either of keywords (either the word Starbucks or the word Costa. Any result that has the search option you excluded will not show up in your results. Google Scholar is a very powerful search engine for scientific literature that is used by many researchers and students. Placing NOT between your search keywords excludes the term after NOT from your search. Placing OR between your search keywords or terms will broaden your search results by returning all possible combinations of your search terms. ![]() Placing AND between your keywords will return results that only include both or all your keywords. Without the quotes, your search engine may return all results that contain each separate word. That is, apple not w/20 pear is not the same as pear not w/20 apple. Example: apple not w/20 pear Unlike the W/ operator, NOT W/ is not symmetrical. Be careful not to accidentally type a dash instead of the minus sign, as this will give completely different search results.Placing quotation marks around a search term or phrase limits your search to that exact term or phrase. The NOT W/N ('not within') operator allows you to search for a word or phrase not in association with another word or phrase. NOT: Putting a minus sign before a word (with no space) excludes the word from the search.When used in a search, the results shown are limited to the information youve provided. The Windows keyboard shortcut for the pipe symbol is ALT + (on the number pad). Operators, also called modifiers, are terms such as AND, NOT, and OR. For example, if you're searching for writing portfolios through a search engine, you may want to filter out results like articles on creating portfolios, as these may clutter your search results. OR: Both the word ‘OR’ and the pipe symbol ( | ) act as the OR operator. The NOT operator, indicated by the minus symbol (-), excludes search results you're not looking for.AND: A space between two terms is interpreted as ‘AND’.For example, although Google supports Boolean search strings containing AND, OR, and NOT (with the minus sign) functionality, you cannot use the NOT/- operator on an OR statement. Search engines like Google use these Boolean operators as follows: What’s especially ironic about the wide spread perception that Boolean Internet search is that most Internet search engines don’t even support full Boolean logic. When NOT is used, all the conditions except the excluded ones must be true. With the OR operator, only one condition has to be met for the result to be ‘true’. Placing the AND operator between two conditions means that both conditions must be met in order for the result to be ‘true’. These symbols are also known as ‘ logical operators’ and are mainly used in programming languages. The operators can be expressed in symbols as well as in words.
