PubMed has a handy tool if you’re trying to locate a specific reference: the single citation matcher. Also, keep in mind that truncation restricts your search to keywords only. Note that if a term is truncated too much, you will get a warning about receiving only the first 600 variations, so you’ll need to lengthen the root word search to get meaningful results. This can be very useful if you’re doing a broad search and will accept multiple forms of your search term, including plurals.Įxample: devel* (retrieves develop, develops, development, developmental, developing, etc.). Use * to replace one or more characters at the end of your search term. Olfactory bulb AND (cell death OR apoptosis) NOT developmentīut you don’t want papers on prenatal development You want all possible articles on this topic Olfactory bulb AND (cell death OR apoptosis) It may be a “good enough” search for you, but keep reading to discover ways to refine your results. Here are the results from a VERY simple search that is the likely starting point for most searchers. Say you’re interested in articles about cell death in the postnatal olfactory bulb. NOT is used when you want articles that EXCLUDE your search term. OR is used when you’re looking for articles that contain AT LEAST ONE of your search terms (broadens your search often used for synonyms).AND is used when you’re looking for articles that contain ALL of your search terms (narrows your search).Boolean operators – AND, OR, NOT – are used to combine search terms, and in PubMed they must be in UPPERCASE. You probably already use them, but may not know their formal name. Improve Your PubMed Searches: Basic Searching 1. Unless you’re avoiding the wet lab, not that I’ve ever used literature searches and background reading as an excuse to step away from the PCR machine, of course. Here are a few basic tips to help you improve your searches on the new PubMed without wasting a lot of time slogging through pages of results, thus getting you back to the bench ASAP. And then you get back about 8 billion results, which – this is just a guess – is far more than you’re likely to read. If you’re like me (before I wised up to the search power of PubMed), you probably just type in your topic of interest and press Go.
