# 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.

Type: | String
Default: | L2
Required: | No
Configuration Section: | VectorIndex
Example: | `DistanceMetric=L2`
