Maximum search limit of 10000 results has been reached

Hi Weaviate community,
we are using Weaviate DB as embeddings storage and performing the similarity search etc. Recently we got the following warning message from the DB
“{“action”:“unlimited_vector_search”,“level”:“warning”,“msg”:“maximum search limit of 10000 results has been reached”,“time”:“2024-01-12T08:23:19Z”}.”
Can you please let us know:
1, what is the reason for that?
2, what is the consequence with this message? Does that mean we are not allowed to save vectors anymore? or we have constrain to perform similarity search? If one of both is “Yes”, can you suggest us any solution on that?

best regards,


Hi @kuanlu3 ! Welcome to our community :hugs:

I believe this is a limit in which Weaviate will stop querying thru the index.

here is where this is raised in code:

So when performing searches or deletions, there are upper limits set to prevent excessive memory usage and long-running requests, which could lead to out-of-memory errors or other performance issues. For example, when deleting objects with a batch delete operation, Weaviate imposes a default limit of 10,000 objects that can be deleted in a single query to protect against unexpected memory surges.

You can still save vectors and objects, however, there is the default limit of 10000 objects to be returned. This value is set by the environment variable QUERY_MAXIMUM_RESULTS as listed here:

Let me know if that helps :slight_smile:
