How many indexes supports per search collection in opensearch serverless?

Question

We are  a customer of AWS opsensearch, and now we are going to use opensearch serverless, and migrate exist data from opensearch to opensearch serverless.
One question is what is the max indexes supported in one collection ? According this [article](https://docs.aws.amazon.com/general/latest/gr/opensearch-service.html) , the max number is 20 indexes in one search collection, but in another [article](https://docs.aws.amazon.com/opensearch-service/latest/developerguide/limits.html#limits-serverless), the limitation is 800 indexes in one  search collection. Which is the exact value ? Thanks!

Accepted Answer

I would like to let you know that OpenSearch serverless now support 1000 indices per collection. Kindly request you to try creating indices as per your requirements and let me know if you face any issues.

I would also like to mention that I have already raised request internally with the relevant documentation team to update the OpenSearch documents to display the updated limits.

Answer

eg, if  I have total 4 OCUs， 2 query OCU and 2 index OCU, if i have 2 collections, then the total indexes can be created is up to 2000. Am i right? @AkashD
