Field qualification in PubMed

There are several ways to search for information in specific fields in PubMed.

The first is to click on the Preview/Index tab located under the query line. Next, select the field that you want from the All Fields drop down. You can then either choose Preview to add the word to the query box or Index to view the word within the alphabetical index.

The second way is to identify the field code or tag and using the appropriate syntax, enter the word(s) on the PubMed query line. While many tags are the same in Ovid and PubMed, some are different.

Here are a few examples:

pizza[ti] AND 2000[dp]
smith[au] AND yale[ad]

Where do you find the field codes or tags?

In the PubMed HELP under Search Field Descriptions and Tags.
And here's a translation table I put together that might help.
