The purpose of the entity matching service is to enable matching in a single list of patients, health workers, facilities or other entities or to find potential matches between two lists of entities.
Potential matching use cases might include:
Ensuring the the entity doesn't exist when entering a new instance of the entity
Duplicate checking during bulk imports.
Analysis of potential duplicates in an existing data set.
Mapping one data set of entities to their corresponding value in another data set.
