`Condition`  <a name="cfn-entityresolution-matchingworkflow-rulecondition-condition"></a>
A statement that specifies the conditions for a matching rule.  
If your data is accurate, use an Exact matching function: `Exact` or `ExactManyToMany`.   
If your data has variations in spelling or pronunciation, use a Fuzzy matching function: `Cosine`, `Levenshtein`, or `Soundex`.   
Use operators if you want to combine (`AND`), separate (`OR`), or group matching functions `(...)`.  
For example: `(Cosine(a, 10) AND Exact(b, true)) OR ExactManyToMany(c, d)`
