A brief list of the most useful PubMed search field tags: these work in HubMed as well, as it's the same search engine.
- Journal Title: J Exp Med [TA]
- Date of Publication: 1998 [DP]
- Author: Jones TL [AU] (usually not necessary, as author names are automatically matched before the rest of the search).
- MeSH Heading: "immune tolerance" [MESH]
- Page Number: 223 [PG]
A quick way to find a specific paper is to use one author name and the starting page number, eg Jones TL [AU] 1343 [PG] (or even just jones tl 1343) - which generally only produces 1 or 2 matches.
Terms are joined with AND by default, but you can use OR or NOT manually.
There is no case sensitivity.
The rest of the tags are described in the PubMed documentation, as is a more detailed guide to searching.
