Welcome to Using Command Search in IEEE Xplore
In this tutorial, you'll learn how to do complex searching in the IEEE Xplore digital library.
To create complex search strings in IEEE Xplore, go to the Advanced Search page and click on Switch to Command Search in the upper right corner.
The command search page allows you to enter keywords, phrases, Boolean expressions and proximity operators.
First, you'll see two radio buttons. These let you choose to search the metadata only—which includes the article title, author names, publication title, index terms and abstract—or the full text and metadata.
Next, there is a drop down menu for the different data fields you can select to search, including document title, abstract, index terms, and other options.
You can also select operators for refining your search. The simple Boolean operators—AND, OR, and NOT—are followed by the proximity operators NEAR and ONEAR.
The NEAR operator keeps words close together, while the ONEAR operator keeps words close together and in the same order. This means using NEAR will return results with the terms in any order, while ONEAR will always keep your first term before the second.
Let's do a search where the document title has the term implantable within three words of the term cardiac, in any order.
Select document title from Data Fields and type in the search string (implantable NEAR/3 cardiac).
You can also use the operators drop down menu to start your search string.
Click the orange search button and you'll see the results all have implantable within three words of cardiac in the document title.
You can go back to the command search page, and click the Reset All button to conduct a new search.
Next, we'll do a nested search using parentheses to combine operators.
A nested search allows you to type in additional search terms, in order to narrow the list of search results. This technique enables you to focus your search and combine topics.
Let's take a look at this type of complex search string.
We start with a parenthesis, followed by UAV or "unmanned aerial vehicle". This phrase is in quotes to force results with those words as an exact phrase. Then we end the parentheses, and add the operator AND. A new parentheses is added with "target tracking" OR "trajectory tracking" inside. These phrases should also be in quotes.
Click on search and you'll see we are getting very specific results about UAV guidance and tracking.
Returning to the command search page, you'll see that there are examples of common search expressions at the bottom of the page.
You can view more by following the blue "See More Examples" link.
Finally, on the right side of the page, there are Learn More About links for Data Fields, Search Examples and Search Operators.
