== Index size guidelines

To ensure optimal performance, follow these recommendations for sizing individual indices on {es-serverless}:

|===
|Use case |Maximum index size |Project configuration

|Vector search
|150GB
|Vector optimized

|General search (non data-stream)
|300GB
|General purpose

|Other uses (non data-stream)
|600GB
|General purpose
|===

For large datasets that exceed the recommended maximum size for a single index, consider splitting your data across smaller indices and using an alias to search them collectively.

These recommendations do not apply to indices using better binary quantization (BBQ). Refer to {ref}/dense-vector.html#dense-vector-quantization[vector quantization] in the core {es} docs for more information.
