# SeedSize

The number of documents needed to form a cluster seed. `SeedSize` allows you to specify the size of the seeds that clusters form around. A seed is the unit that a cluster is based on, and it is built from documents in the IDOL Server data index that contain similar concepts.

`SeedSize` represents the size of the document group that is required for the document concepts to form the basis of a cluster. You can use SeedBindLevel to specify the conceptual similarity that the documents must have to each other to form a seed.
