My 1L legal research course emphasizes the importance of utilizing all the resources at one’s disposal—what I refer to as “the tools in your toolbox.” This means navigating multiple databases, exploring their resources, and mastering various search functions. Parallel searching on Westlaw is yet another tool for legal researchers to use.

Where do you find Parallel Search?
You can find Parallel Search in the Key Features section under the main search box on the home page.
What does it do?
According to Westlaw, Parallel Search allows you to “enter a sentence or legal concept to find cases with conceptually similar sentences. Parallel Search understands synonyms and relationships between words and ideas, so it finds relevant cases even if they do not use your exact words.” You will get up to 25 results.
Tips for using Parallel Search
- You can limit your search by jurisdiction.
- For the best results, construct your search as a full sentence of about 5 to 30 words. Punctuation matters, but capitalization does not.
- Include both legal concepts and facts.
- Small changes can impact your results, so play around with your wording if you are not getting what you need.
- If you search for a highly quoted sentence, you will likely end up with a lot of results that include that sentence verbatim.
