MEDLINE records contain a powerful tool for subject searching:
Medical Subject Headings, or MeSH. They are in the MESH field
in MEDLINE on SilverPlatter. Search in mesh to retrieve all
MESH headings, and in mjme to retrieve major headings only. The
following screens describe MeSH headings and how to search them in
MEDLINE on SilverPlatter.
When an article is indexed for MEDLINE, the indexer at NLM assigns
several single- or multi-word terms for the most specific concepts
covered in the article. These terms, or MeSH headings, are selected
from the NLM authority list for subject analysis of the biomedical
literature.
Press PgDn for more information.

MeSH headings are powerful searching tools. They locate documents
by assigned controlled vocabulary, not free text words, and are
independent of the occurrence of specific words in any other field.
For example, the search hypertension in mesh retrieves all documents
about that topic, although the word hypertension may not appear in
the title or abstract. MeSH headings help you focus your search and
eliminate out-of-context occurrences.
Subheadings
Indexers often attach subheadings to a MeSH heading to describe the
topic more specifically. Examples of subheadings are: diagnosis;
drug effects; therapy.

The MESH field contains all of the MeSH headings that are in the
record. Headings preceded by an asterisk (*) are major headings,
which represent the central concepts of the article. Searching
in mjme limits your search to articles in which your topic is a focal
point, while searching in mesh retrieves all articles about the topic.
