1 00:00:00,000 --> 00:00:00,600 2 00:00:00,600 --> 00:00:03,966 Using Command Search in IEEE Xplore 3 00:00:03,966 --> 00:00:07,732 To compose free-form, complex search queries, 4 00:00:07,733 --> 00:00:09,866 use Command Search. 5 00:00:09,866 --> 00:00:15,532 Find the Command Search page by clicking on Advanced Search just below the Global Search box 6 00:00:15,533 --> 00:00:18,733 and selecting the second tab. 7 00:00:18,733 --> 00:00:23,866 The Command Search page allows you to combine keywords using Boolean expressions 8 00:00:23,866 --> 00:00:28,999 and proximity operators, as well as search within a variety of fields. 9 00:00:29,000 --> 00:00:38,500 If you are using operators, you can enter up to 20 words in each search clause. Although parentheses are not required, they can 10 00:00:38,500 --> 00:00:44,833 be helpful by allowing you to group together and prioritize parts of the query. 11 00:00:44,833 --> 00:00:46,633 Let's do a search. 12 00:00:46,633 --> 00:00:52,299 You can use the drop-down menus to choose Data Fields. If you select to search within 13 00:00:52,300 --> 00:00:57,966 a data field, you must enter the data field before each keyword. 14 00:00:57,966 --> 00:01:04,232 If you do not select a data field, your keywords will be searched in All Metadata. Metadata 15 00:01:04,233 --> 00:01:10,499 includes article title, author names, publication title, index terms, 16 00:01:10,500 --> 00:01:13,800 abstract, and other data fields. 17 00:01:13,800 --> 00:01:18,233 You can use the drop-down menus to help enter operators into the text box or you can 18 00:01:18,233 --> 00:01:25,299 type them directly into the box. Remember, operators need to be in all capital letters. 19 00:01:25,300 --> 00:01:35,566 As with other search boxes in IEEE Xplore, if you don't enter an operator, the search engine will AND together your concepts. 20 00:01:35,566 --> 00:01:42,432 Now, let's talk about the proximity operators. The NEAR operator keeps words close together while 21 00:01:42,433 --> 00:01:49,299 the ONEAR operator keeps words close together and in the same order. 22 00:01:49,300 --> 00:01:54,966 Suppose I'm looking for papers written about the haptic communication of touchscreens. 23 00:01:54,966 --> 00:02:02,832 I know that touchscreen is sometimes one word and sometimes two words and haptic is sometimes called kinesthetic. 24 00:02:02,833 --> 00:02:12,766 So let me structure my search to capture all these terms. I also need to keep the terms close together so I'll use the proximity operator 25 00:02:12,766 --> 00:02:18,399 NEAR. The one-word touchscreen, haptic and kinesthetic will all be automatically stemmed, which is 26 00:02:18,400 --> 00:02:24,066 the default in IEEE Xplore, so I don't have to worry about plurals. 27 00:02:24,066 --> 00:02:32,166 Since I'm using exact phrase quotation marks around the two word "touch screen," auto-stemming will be turned off. 28 00:02:32,166 --> 00:02:37,599 The words within quotation marks have to be an exact match. To allow the search engine to find "touch screens" (plural), 29 00:02:37,600 --> 00:02:43,033 I'll need to add a wildcard there. 30 00:02:43,033 --> 00:02:55,433 IEEE Xplore supports 2 wildcards, the asterisk wildcard represents any or no characters and the question mark wildcard represents a single 31 00:02:55,433 --> 00:03:04,733 character. Wildcards can be used with any word over 3 characters, except in the author name field where the minimum is 2 characters. 32 00:03:04,733 --> 00:03:09,899 You can use up to 6 wildcards in your search string. 33 00:03:09,900 --> 00:03:18,900 With any proximity operator, I need to enter a number telling the search engine how many words can be in between my 2 concepts. 34 00:03:18,900 --> 00:03:25,400 I'll enter the number 5 after NEAR/ to keep my concepts within 5 words of one another. 35 00:03:25,400 --> 00:03:31,933 I'm also using parentheses to keep my OR terms grouped together. 36 00:03:31,933 --> 00:03:36,699 Click the blue Search button and you'll see the results have both 1 word and 2 word 37 00:03:36,700 --> 00:03:41,466 variants of touchscreen and plurals are captured for both. 38 00:03:41,466 --> 00:03:46,266 There are lots of other types of searches you can do on the Command Search page. 39 00:03:46,266 --> 00:03:50,632 Click on Search Examples to the right of the search box to see some ideas 40 00:03:50,633 --> 00:03:54,033 or click on the other links to learn more about data fields 41 00:03:54,033 --> 00:04:01,933 and search operators.
