Final answer:
To locate knowledge base articles containing the specified keywords, use the 'OR' operator between the keywords in the search string.
Step-by-step explanation:
To configure the search to locate knowledge base articles that contain the words 'Elevator', 'Motor', and 'Sizing' anywhere in an article, you will use the Boolean operator 'OR'. By using 'OR' between the keywords, you ensure that the search will retrieve articles that contain any of these words.
For example, you can use the search string 'Elevator OR Motor OR Sizing' to find articles with any of these keywords. This allows you to locate relevant knowledge base articles regardless of the product they refer to.
