Note: Beginning June 1, 2021, users of NCBI services will need to login with their MSU Net ID instead of a NCBI-generated account. The NLM has more information about this change and how to link your existing NCBI account with your MSU Net ID. A Microsoft Word document containing step by step instructions is avaialble for download.
If you are starting your search, trying use keywords, rather than full sentences.
If you are searching for a phrase, such as functional adaptation, put the entire phrase in double quotes. This will tell the database to only find results that contain the exact phrase, rather than one or two of the individual words.
If you have two or more words or concepts that you want to find, use AND (must be capitalized) to tell the search engine to only look for items that contain both words.
If you can think of common synonyms for one of your keywords, you can have the database search for articles that contain either one by using OR (always capitalize!)
