public class SimpleIndexConfig extends IndexConfig<Object>
Configuration class for SIMPLE vector indexing.

Simple index uses standard Coherence index on a vector field, in order to avoid chunk and vector deserialization when performing similarity search.

Unlike HnswIndex and BinaryQuantIndex, simple index cannot be queried directly, and requires vector distance calculation to be performed for each document chunk in the store. That means that it will always provide the most accurate results, at the cost of performance.

Unless the store is fairly small, HnswIndex and BinaryQuantIndex are better options for most use cases, abd should be preferred.
