Just like conducting a higher degree by research (HDR) project, a comprehensive literature search starts with effective planning. A literature search plan can:
The process of finding, evaluating and selecting literature for your thesis is not linear. You may need to revisit several steps throughout the process to gather information.
The below flowchart provides a visual depiction of the iterative nature of researching, and some reflective questions to guide you.
The flowchart depicted includes the following steps:
Before searching literature in databases, you need to formulate a search query based on your research topic. A search query is the translation of your research topic into searchable keywords and phrases that can be used in databases and Google Scholar.
This sounds obvious, but to begin searching you need to be clear about your topic.
Write down a summary of your topic and check that it's clear and focused. This will help guide you in the sort of information you are looking for.
Highlight, underline or circle the keywords or main concepts in your summary. These words can help you build your search strategy and set parameters.
Authors will use different terminology for the same concept so it's important to think of alternative words for each of your concepts. These can be synonyms, related words, abbreviations, acronyms and other words that are specific to your topic.
Doing this will ensure that you don't miss out on any useful articles that you might otherwise miss if you only use one or two search terms.
Use Boolean operators AND OR, NOT to combine these terms into a meaningful search. These operators are a means of combining search terms to broaden or narrow search results.
AND Use AND to retrieve documents that contain both of the specified search terms.
OR Use the OR search operator to retrieve documents that contain one or both specified search terms
NOT Use the NOT search operator to retrieve documents that do not contact the specified term.
Follow the example below of how the steps previously outlined have been used in a search planner.
