Command Search in IEEE Xplore

[Title] Using Command Search in IEEE Xplore To compose freeform search queries in IEEE Xplore, use the Command Search page, which can be found under
Other Search Options or as the second tab on the Advanced Search page. The Command Search page allows you to enter up to 40 keywords and a variety of field codes, Boolean expressions, and proximity operators. If you are using operators, you can enter up to 15 words for each search clause. Although parentheses are not always required, they can be helpful by allowing you to group together and prioritize parts of the query. Let’s do a search. First, you will see two radio buttons. These let you choose to search Metadata Only or Full Text and Metadata. Metadata includes Article Title, Author Names, Publication Title, Index Terms, Abstract, and other data fields. You can use the dropdown menus to help enter operators or data fields into the text box, or you can just type directly into the box. Remember to follow all the syntax and that operators need to be in capital letters. A few tips here: As with other search boxes in IEEE Xplore, if you don’t enter an operator, the search engine will AND together your concepts. Now let’s talk about proximity operators. The NEAR operator keeps words close together, while the ONEAR operator keeps words close together and in the same order. Suppose I am looking for papers written about haptic communication of touch screens. I know that ‘touch screen’ is sometimes one word (touchscreen) and sometimes two words (touch screen) and ‘haptic’ is sometimes called ‘kinesthetic’. So let me structure my search to capture all these terms. I also need to keep the terms close together, so I will use the proximity operator NEAR. The one word ‘touchscreen’, ‘haptic’, and ‘kinesthetic’ will all be automatically stemmed, which is the default in IEEE Xplore, so I don’t have to worry about plurals. Since I’m using exact phrase quotation marks around the
two-word ‘touch screen’, auto-stemming will be turned off. The words within quotation marks have to be an exact match. To allow the search engine to also find ‘touch screens’, plural, I will need to add a wildcard there. IEEE Xplore supports two wildcards. The asterisk (*) wildcard represents any or no characters and the question mark (?) wildcard represents a single character. Wildcards can be used with any word over three characters except in the Author Name field where the
minimum is two characters. You can use up to five wildcards in your search string. With any proximity operator, I need to enter a number telling the search engine how many words can be in between
my two concepts. I will enter the number ‘5’ after ‘NEAR/’ to keep my concepts within 5 words of one another. I’m also using parentheses to keep my OR terms
grouped together. Now click the orange Search button and you will see in your results that there are both one-word and two-word variants of ‘touch screen’ and plurals are captured for both. There are a lot of other types of searches you can do with the Command Search page. See the search expression examples at the bottom or click on the links for more help. This has been Command Search on IEEE Xplore. Thanks for watching.
