This page shows you how to use the delete endpoint to remove documents from a collection.

​
Delete documents by IDs

Since LambdaDB documents can always be efficiently accessed using their ID, deleting by ID is the most efficient way to remove specific records. 
from lambdadb import LambdaDB

lambda_db = LambdaDB(
    server_url="PROJECT_URL",
    project_api_key="YOUR_API_KEY"
)

res = lambda_db.collections.docs.delete(
    collection_name="your_collection_name", 
    ids=[
        "example-doc-id-1",
        "example-doc-id-2",
    ]
)

​
Delete documents by query

To delete documents based on their data, pass a filter query to the delete operation. This deletes all document matching the filter query. For example, to delete all documents with genre “documentary” and year 2019 from a collection, use the following code: 
res = lambda_db.collections.docs.delete(
    collection_name="your_collection_name",
    filter_={
        "queryString": {
            "query": "genre:documentary AND year:2019"
        }
    }
)

​
Delete an entire collection

To remove all documents from a collection, delete the collection and recreate it
