Once you have identified a topic, select the terms and phrases that are essential to understanding the topic.
Explore Subject/Heading/Descriptors/Major Concepts found when during a test search in a relevant database. Use these found terms and phases in a new search.
Topic – "In the yellow fever and dengue vector Aedes aegypti, both sexes interact acoustically by shifting their flight tones to match, resulting in a courtship duet" (Lauren J. Cator, Lauren J., Arthur, Ben J., Harrington, Laura C. & Hoy, Ronald, R., 2009).
Keywords: Aedes aegypti, acoustics, mating
Subjects (found): Behavior; Reproduction; mating success; genetic quality; harmonic frequency; bioacoustic signal; flight tone; harmonic convergence; signal coevolution
Once you have identified the keywords, find a way to think of related terms and phrases. If you are having trouble identifying additional keywords, thesauri, dictionaries, encyclopedias, and online encyclopedias like Wikipedia can be great places to look for inspiration even though this background might not be specifically used in the project.
Using Database Subject Thesauri & Terms
Take note of Subject/Heading/Descriptors found during a test search in a relevant database. Use these found terms and phases in a new search.
Many scientific dasebases use standardized subject headings - look for links to Subjects, Headings, MeSH, Major Concepts or Thesaurus to explore the standard terms used to group similar articles. These terms can be used to help generate more ideas for your research and make your searches more precise.
Build a good search by doing a broad search with no limits. Be prepared to do several similar fast searches, quickly scanning the titles found. Redo the search in steps, adding one limit at each step. This allows you to see where things start getting better or go wrong. Do NOT limit to full text unless there are still too many records in the final search. The Click here for more information link will very, very often connect to full text in one of many other UT Arlington library databases.
For example: In the database Biological Abstracts, using the Major Concepts link, typing in reproduction will display the following -
Scope Note: The study of the processes involved in the production of offspring. Includes studies on all forms of sexual and asexual reproduction and reproductive structures in plants. Examples include fission, sporulation, cell division of a single cell organism, parthenogenesis, fertilization, syngamy, pollination, and viral reproduction. Examples include fission, sporulation, cell division of a single cell organism, parthenogenesis, fertilization, syngamy, pollination, and viral reproduction.
For non-clinical studies, see Reproductive System.

It is important to know when to broaden or narrow/limit a search. Broaden the search if there are few or inaccurate results.
Ways of broadening a search:
Narrow or limit thesearch when - there are a very large number of hits or if the search topic is very broad.
Ways of limiting/narrowing a search:
Articles that have been evaluated by other professionals in the field to check for accuracy and adherence to disciplinary standards.
