Match level

Applicable to declarative match rules with a fuzzy match strategy. The match level indicates the level of fuzzy matching that you want to perform on your data. The number of matching records that a declarative match rule generates depends on the match level.
The following table describes the match levels:
Match Level
Description
Conservative
Performs stringent matching that results in few matching records. Some matching records might slip through the match process.
Loose
Performs lenient matching that results in a significant number of matching records. Some records might be incorrect matches.
Use the loose match level in a declarative match rule with a manual merge strategy to capture the potential matching records that the stringent match rules might miss. A user can manually review these matching records before merging them.
Typical
Use in most matching scenarios to get an optimal number of matching records.
