- Text Word searches title, abstract, author keywords and MeSH terms (but do not explode MeSH terms).
- You can search with MeSH-terms (MeSH Terms / MeSH Major Topic) . If you don't know the exact MeSH term, serch for it in MeSH Database instead.
- Notice that All Fields search uses Automatic Term Mapping.

Proximity searching
Proximity operators / Finding scientific information
You can use proximity searching to search for multiple terms appearing in any order within a specified distance of one another. Stopwords included in quoted terms for proximity search are searched like regular keywords.
To create a proximity search in PubMed, enter your terms using the following format: "search terms"[field:~N]
- Search terms: two or more words enclosed in double quotes
- Field: the search field tag for [Title], [Title/Abstract], or [Affiliation] fields
- N: the maximum number of words appearing between your search terms
Examples:
"pain management"[Title/Abstract:~2]
"postoperative pain management"[Title/Abstract:~2]
"university oulu"[Affiliation:~1]
Proximity searching is not compatible with truncation (*)
