While searching for literature on a topic you wish to explore, consider the following :
AND
OR
NOT
Use parentheses to set the order of execution of the Boolean logic.
Parentheses work in most but not all systems (e.g., they work on the Ovid, PubMed, EBSCOhost, ProQuest, Scopus, and Web of Science platforms, but can be ignored in other search engines). Try your search with and without the parentheses. If you notice a difference in your search results, the parentheses are likely working.
e.g., (chest OR thorax OR thoracic) AND (imaging OR radiographs OR radiography)
Boolean operators can be placed between your search terms to narrow or broaden a search, or to exclude search terms.
You will find below a brief video on how to use the boolean operators:
Fun fact, this also works in Google Scholar.
Below is a selection of subject-specific and multidisciplinary database.
Subject-specific databases offer you more precise results and less results, but given that research is more and more interdisciplinary, you may miss important papers, books, book chapters and conference proceedings.
A multidisciplinary database offers a larger amont of results, but may also yield too many results to analyze. However, you might find research relevant to your topic from other fields of research that are not included in a subject-specific database.
