Develop a search statement

Your concept map will have identified the component subtopics of your research question. Key phrases and keywords that aptly identify and define each subtopic element will appear as captions on your concept map. Another way of describing subtopic captions would be to label them as
"the big ideas"; the major aspects of your deconstructed research question / research problem.

Your initial search strategy will employ these key phrases and keywords captions as Boolean search terms.

To adequately broaden your search strategy however in order to become a comprehensive literature search you will need to brainstorm related, alternative, variant terminology. What other terms could be used to describe your research question components? Study a few common engineering terminology examples which are spelt out in the three tables below. 

You need to record your related terms and synonyms (words with the same or similar meaning) synonymous phrases with their variant spellings as they must be integrated into your search strategy. Group the keyword synonyms into your Boolean search strategy, the template for which is in Question 2 of your worksheet task; Developing a Search Statement.  Synonyms and related terms get grouped inside of a set of parenthesis with each linked by the OR search operator.
