Using CINAHL/MeSH Headings

Subject terms are assigned based on article content, allowing you to create a targeted search. When you click the Suggest Subject Terms box above the Find field prior to conducting a search, your terms are searched against the CINAHL Headings or MeSh Headings authority, depending on the database being searched. From there, you can select headings and subheadings to refine your search.

To use CINAHL/MeSH headings:

  1. Enter your search terms in the Find field, check the Suggest Subject Terms box and click Search.

    Note: You can also browse CINAHL or MeSH Headings by clicking the link in the top toolbar.

Using Explode and Major Concept


Explode

When you Explode a term, you create a search query that “explodes” the subject heading. The headings are exploded to retrieve all references indexed to that term as well as all references indexed to any narrower subject terms.

In a database with a tree, such as MeSH or CINAHL Headings, exploding retrieves all documents containing any of the subject terms below the term you selected. In other databases, exploding retrieves all documents containing the selected term, as well as any of its first level of narrower terms. If a plus sign (+) appears next to a narrower or related term, there are narrower terms below it.

Major Concept

When you select Major Concept for a term, you create a search query that finds only records for which the subject heading is a major point of the article. Searches are limited with specific qualifiers (subheadings) to improve the precision of the search, and limited to major subject headings indicate the main concept of an article.

Combining Explode and Major Concept

If you select both Explode and Major Concept, you retrieve all references indexed to your term (and its narrower terms) and all articles for which the subject heading is a major point of the article.
