How to delete with Filter

Support
1

Hi,

Can we delete data using a filter? According to the documentation at weaviate.data — Weaviate Python Client 3.20.2.dev0+gd241333.d20230614 documentation , it seems that we can only delete data by specifying the UUID.

Alternatively, we can apply the filter to retrieve the data using the additional_properties parameter and then delete each entry individually. However, I noticed that there is a limit parameter for the get method (default is 100). Is there a way to retrieve all the documents without using the limit parameter?

Any assistance would be greatly appreciated.

Hey, Thanks for your responses!

and we don’t need to adjust the number of objects returned, right? I think it’s 10k by default, not 100 like get function.

Correct, the default value of objects deleted by a single query is 10k.
