Truncation

Truncation can be used when you want PubMed to find all terms that begin with a given text string. Truncation is represented by the asterisk (*), sometimes referred to as a "wildcard." For example, let's say you are trying to search all terms that have the root, mimic. If you search mimic* PubMed will retrieve words such as mimic, mimics, mimicing, etc. PubMed has no single character truncation symbol. [Show Me]

Truncation Tips:

• PubMed restricts retrieval to the first 600 variations of the truncated term. When this occurs, PubMed will display a warning message. [Show Me]
  
  
• Truncation turns off automatic term mapping and the automatic explosion of MeSH terms. For example, brain cancer* will not map to the MeSH term Brain Neoplasms or include any of the more specific indentions, such as Cerebral Ventricle Neoplasms, Neurocytoma, or Supratentorial Neoplasms.
