In PubMed you can use Pearl Searching through the MeSH (Medical Subject Heading) Thesaurus. There you can find narrower terms and you can combine terms. To do this: open an article that is directly focused on your topic. Scroll down to the MeSH headings and click on the heading of interest. Explore the MeSH thesaurus entry for that subject and select what you want to construct your next search.
In PubMed, if you want to combine searches, go to "Advanced." There you will find your recent searches. Use the numbers to combine them. Example: #4 and (#3 or #2)
