Searching Ovid Medline
- Ovid Medline defaults to the Advanced Search tab
- Divide the research topic into conceptual parts and do one aspect of the search (e.g. a specific disease/condition) at a time
- Search example: Citations on controlling type 2 diabetes and obesity with exercise can be divided into 3 concepts: type 2 diabetes, obesity (prevention and control), and exercise. Type the first concept into the search box, leave the Map Term to Subject Heading box checked and click Search:
- Ovid Medline uses subject headings to describe concepts, rather than relying on an author's keywords. Ovid suggests subject headings that best match your entry terms.
- On the Mapping page, leave the Auto-Explode box checked so that your our search includes narrower subjects that fall under this subject heading
- Select Focus if it seems that the subject heading may be too broad:
- Keywords can also be used to search for concepts for which there is no good subject heading or to search for brand or model names
- Scope notes are used to find more information out about a term. Click on the 'i' icon to read the scope note
- To search using a keyword, select the mp line at the bottom of the Mapping display:
- Subheadings significantly narrow a subject search. If there is likely to be a lot published about a topic, choose one or more subheadings to narrow results (e.g. Prevention & Control in the image below) or choose all subheadings by clicking the Continue button:
Adding Additional Concepts to a Search
- Repeat the above steps for the second and third aspects of the search. For the example above, you would next add Obesity in the search box and complete the process, then continue again with the term Exercise
- Combine two concepts by clicking the check box to the left of the set display and then click on the AND button to narrow results to all topics. Click on the OR button to combine "like" terms:
- Once you have combined your sets, you can refine results by using Limits. Commonly-applied limits in Ovid Medline are listed directly under the search box and include parameters such as English language articles, range of publication years, and articles about Humans. Click on the Additional Limits button to see the full suite of Limits --including Age Groups.
- The latest set created in Ovid Medline is always available directly underneath the search box. To view a previously created set, click on the Display link next to that set
- To view more detailed information about a citation, click on Complete Reference
- Avoid using the Find Citing Articles link as it searches only a small portion of the Ovid Medline database
