Question

Hey,
I am trying to delete the Azure AI Search index that I created using the Lama index. I reviewed the documentation but could not find any reference for it.

Can you help me with it by pointing me in the right direction or documentation?

Thanks in advance

Hey, @krupalsmart97! 👋 I'm here to help you with bugs, questions, or becoming a contributor. Let's squash those bugs together!

To delete an Azure AI Search index using the LlamaIndex framework, you can use the delete or adelete methods. Here's how you can do it:

1. Synchronous Deletion: Use the delete method to delete documents from the AI Search Index by specifying the ref_doc_id:

   def delete(self, ref_doc_id: str, **delete_kwargs: Any) -> None:
       if not self._index_exists(self._index_name):
           return
   
       filter = f'{self._field_mapping["doc_id"]} eq \'{ref_doc_id}\''
       batch_size = 1000
   
       while True:
           results = self._search_client.search(
               search_text="*",
               filter=filter,
               top=batch_size,
           )
   
           docs_to_delete = [
               {"id": result[self._field_mapping["id"]]} for result in results
           ]
   
           if docs_to_delete:
               self._search_client.delete_documents(docs_to_delete)
           else:
               break

2. Asynchronous Deletion: Use the adelete method for asynchronous deletion:

   async def adelete(self, ref_doc_id: str, **delete_kwargs: Any) -> None:
       if not await self._aindex_exists(self._index_name):
           return
   
       filter = f'{self._field_mapping["doc_id"]} eq \'{ref_doc_id}\''
       batch_size = 1000
   
       while True:
           results = await self._async_search_client.search(
               search_text="*",
               filter=filter,
               top=batch_size,
           )
   
           docs_to_delete = [
               {"id": result[self._field_mapping["id"]]} async for result in results
           ]
   
           if docs_to_delete:
               await self._async_search_client.delete_documents(docs_to_delete)
           else:
               break

These methods locate documents to delete using a filter based on the ref_doc_id and delete them in batches ^[1].

@dosu , so I know that I can delete a document indexed inside an index but my question is how to delete the entire index not just one document

[dosubot]

Could you provide more details about the tools or SDKs you're using to interact with Azure AI Search? This will help me guide you on how to delete the entire index.

@dosu I am using the llama index for interaction

The LlamaIndex framework does not explicitly provide a method to delete an entire Azure AI Search index. However, you can manage Azure AI Search indexes using the Azure SDK for Python, which provides the necessary functionality to delete an entire index.

Here's a basic example of how you can delete an Azure AI Search index using the Azure SDK:

from azure.search.documents.indexes import SearchIndexClient
from azure.core.credentials import AzureKeyCredential

# Replace with your Azure Search service details
endpoint = "https://<your-service-name>.search.windows.net"
admin_key = "<your-admin-key>"
index_name = "<your-index-name>"

# Create a client
client = SearchIndexClient(endpoint=endpoint, credential=AzureKeyCredential(admin_key))

# Delete the index
client.delete_index(index_name)

Make sure to replace <your-service-name>, <your-admin-key>, and <your-index-name> with your actual Azure Search service name, admin key, and the name of the index you want to delete. This approach uses the Azure SDK directly to manage the index lifecycle.
