This has not yet been reflected in the below search strategy. Since November 2022 it also allows proximity searching. PubMed allows truncation searching, in which an asterisk can substitute variant endings. This is the Concept Table for Medline via PubMed. animal adj3 therapy picks up animal therapy, animal based therapy, animal assisted play therapy, therapy using animals. Adj2 finds terms in any order and with one word (or none) between them.Į.g. To apply adjacency, separate your search terms with the ADJ operator and a number from 1 to 99. behavi o?r picks up behavior and behaviourĪDJn is a positional operator that lets you retrieve records that contain your terms (in any order) within a specified number (n) of words of each other. It is useful for retrieving records with British and American spelling variations because it finds words whether or not the extra character is present.Į.g. The optional wild card character stands for zero or one characters within a word or at the end of a word. therap*3 picks ups therapy and therapies, but not therapeutic Limited right-hand truncation restricts the number of characters following the wordĮ.g. stimulat* picks up stimulation, stimulated, stimulus Every item about dengue would be returned, as would those that discuss both of the other two.E.g. Modify our Boolean search string examples according to your needs. And, if you already have a candidate in mind, use Boolean search strings to discover their resume on various platforms. Since dengue fever has been a concern for over 250 years, this search would yield different results. Sourcing resumes with Boolean search helps you better evaluate passive candidates. dengue OR ( malaria AND zika) = every article about dengue, or those that discuss both zika and malaria.As the zika virus has only recently been a serious issue, this would limit the number of results. Every item returned would mention zika, and either dengue or malaria. ( dengue OR malaria) AND zika = articles about dengue or malaria, that also discuss zika.For example:ĭengue OR malaria AND zika can be interpreted as To make sure you get the search you want, use parentheses - every database follows those rules. Example search statement: drug abuse AND teenagers: This search retrieves. Different databases have different rules about combining searches. AND is used between keywords with different meanings. Think of your search in concepts, then put those concepts inside parentheses. Searching on "dengue fever" will return only items with that exact phrase. If you're searching for a phrase rather than just a single word, you can group the words together with quotation marks. Note: sometimes AND NOT is used serves the same function as NOT. Searching on malaria NOT zika returns items that are about malaria, but will specifically NOT return items that contain the word zika.
