If you type a term that can have other common endings, these endings might also be included in your search results. For example, if you type brown, you will get results that contain brown, browns and browning.
Occasionally you will also get results that include a shorter version of your term. Typing toxicity will return results with toxic, and vice versa.
If you sort your results by relevancy (the default setting) exact matches to what you typed will appear at the top of your results list.
