@Vaibhav Patil Thanks for reaching here!
The error message you are seeing indicates that the maximum number of indexes allowed for your Azure AI Search service has been exceeded. In this case, the error message specifically mentions that the maximum number of indexes allowed is 3, and that you have already reached this limit.
To resolve this issue, you will need to either delete unused indexes or upgrade your service to a higher pricing tier that allows for more indexes.
Refer- https://learn.microsoft.com/en-us/azure/search/search-limits-quotas-capacity#index-limits
If you have unused indexes that you no longer need, you can delete them to free up space for new indexes. To delete an index, you can use the Azure portal or the Azure AI Search REST API.
Refer- https://learn.microsoft.com/en-us/rest/api/searchservice/delete-index
Alternatively, you can upgrade your service to a higher pricing tier that allows for more indexes. You can find more information about the pricing tiers and their features on the Azure AI Search pricing page. https://learn.microsoft.com/en-us/azure/search/search-limits-quotas-capacity#index-limits
Once you have freed up space for new indexes or upgraded your service, you should be able to create new indexes without encountering this error.
I hope this helps! Let me know if you have any other questions.
