DistanceMetric
The metric to use to determine the distance between vectors in your index. You can use one of the following values:
-
L2
-
Cosine
-
InnerProduct. If you use InnerProduct then your vectors must be pre-normalized.
NOTE: You can set the DistanceMetric configuration parameter as a field property for a VectorType to set the distance metric individually for different vector fields. In this case, the value the field property takes precedence. The value in the [VectorIndex] section is the default value when the field property value is not set.
