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

Truncation
Tips:
- PubMed restricts
retrieval to the first 600 variations of the truncated term. When
this occurs, PubMed will display a warning message. [Show

- 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.
