Unlike [Screena Firm](https://developer.screena.ai/#screena-firm), which is designed to search on lists/datasets, [Screena One](https://developer.screena.ai/#screena-one) and [Screena Plus](https://developer.screena.ai/#screena-plus) are two microservices designed to match one name against another and return a similarity score.

In this context, Screena One and Screena Plus usually integrate on top of legacy screening solutions with no core machine learning capabilities to help reduce false positives.

Screena One will only match one name against another, while Screena Plus is an extension of Screena One to match names plus secondary attributes such as dates and addresses.
