CINAHL 5 – Combining Search Lines


This screencast will show you how to combine
the lines in your search using AND, and OR, known in the
library world as Boolean Logic operators. In CINAHL, lines of search are combined in
the search history section of the page. If you have used the structured approach demonstrated
in previous videos, you should have heading searches and textword
searches for each concept, all on separate lines. Remember
the goal of this search is to find all articles that discuss the concepts of pet therapy AND
nursing homes. Before you combine your concepts, you first
want to combine all of the lines that are searching the first
concept – in this case nursing homes. When combining synonyms, we always use the
operator OR. So
let’s click on the boxes on the left side of the page for every line related to the
concept of nursing homes, including both CINAHL headings and text words. Once you’ve done this, you can then click
on the button here that says search with OR. This will open up a new page of results, and
you’ll also see that a new line has been added to the top of our search history
list here. This line shows the results of combining the
search lines related to our first concept. Now, we can repeat the process for each subsequent
concept, selecting each one and then searching them
with OR. Now we have two new lines at the top of our
search history, one for pet therapy and one for nursing homes. From here, we can combine the concepts
to get our final results. When combining different concepts we always
use AND in order to find the overlap. Click on both of your combined lines, and
then click search with and. This produces another
new line at the top that displays the overall results of the combined elements of your search. To view
the results, look to the right side of page under the actions column click on view results,
under the actions column. If you find that you are not retrieving enough
or too many results, you may have to add or remove a concept, think of more synonyms,
or make changes to your textword queries. Often a good
search requires a few attempts at different logical combinations and goes through a number
of revisions. In the next video, I will show you how to
apply filters to your search.
