Note: most databases and search engines assume AND if no operator is used between terms.
|To find results containing all terms or concepts. Narrows results.||primates AND enrichment|
|To find results containing any of the terms. Used for combining synonyms or similar concepts. Broadens results.||mouse OR murine OR mus musculus|
|Used to exclude a term from all results. Narrows results, but can often exclude relevant articles. Use with caution.||animal models NOT primates|
(eye OR ocular OR cornea) AND toxicity testing AND (alternatives OR biological assay OR in vitro OR ex vivo OR culture)
Can be used to include all forms of a word in a search without having to type each one out. For example, in PubMed:
Most databases use the asterisk (*) for truncation, but not all. If you are unsure, you can usually find the appropriate symbol under Help.
