To use research terms effectively for a thesis, you need to identify the core concepts of your research question, generate a list of synonyms, and combine them using search operators to find relevant literature in academic databases.
Building a solid search strategy is the foundation of a strong literature review. Using the right academic vocabulary ensures you don't miss critical studies while keeping your search results focused and manageable. Here is a step-by-step guide to building and applying your research terms.
Extract Core Concepts
Start with your main research question or thesis statement and strip away the filler words. You only want to keep the primary variables or subjects. For example, if your thesis question is "How does remote work impact employee productivity in the tech industry?", your core concepts are remote work, employee productivity, and tech industry.
Build a Keyword Bank
Academic authors often use different terminology to describe the exact same concepts. To capture all relevant literature, create a list of synonyms, broader terms, and narrower terms for each of your core concepts.
- Remote work: telecommuting, work from home, distributed teams, hybrid work.
- Productivity: performance, output, efficiency, job satisfaction.
- Tech industry: software companies, IT sector, technology firms.
Combine Terms with Boolean Operators
Once you have your keyword bank, use Boolean operators to connect them in academic search engines like PubMed, Scopus, or Web of Science.
- OR: Broadens your search by connecting synonyms. It tells the database to find papers containing any of the terms (e.g., "remote work" OR "telecommuting").
- AND: Narrows your search by requiring all concepts to be present in the paper (e.g., "remote work" AND "productivity").
- NOT: Excludes specific terms to remove irrelevant results (e.g., "productivity" NOT "manufacturing").
Execute and Refine Your Search Strategy
Test your term combinations in academic databases using quotation marks for exact phrase searching. If you are getting thousands of irrelevant results, you might need to use more specific terms. Traditional keyword searching can sometimes be frustrating if authors use unexpected phrasing, but tools like WisPaper's Scholar Search can help by understanding your underlying research intent rather than just matching exact keywords, automatically filtering out up to 90% of the noise.
As you start finding relevant papers, pay close attention to the vocabulary used in their abstracts and the author-provided keywords. You will often discover new, highly specific academic terms that you can feed back into your keyword bank to continuously improve your literature search.
