Weaviate Invalid Sort Order

The sort order specified in the query is invalid.

Understanding Weaviate and Its Purpose

Weaviate is an open-source vector search engine and database that allows you to store, search, and manage data using machine learning models. It is designed to handle unstructured data and provides capabilities for semantic search, making it a powerful tool for applications that require natural language processing and AI-driven insights. Weaviate supports various data types and offers a flexible schema to accommodate diverse use cases.

Identifying the Symptom: Invalid Sort Order

When working with Weaviate, you might encounter an error related to an 'Invalid Sort Order'. This issue typically arises when executing a query that includes sorting parameters. The error message indicates that the sort order specified is not recognized or supported by Weaviate.

Common Error Message

The error message might look something like this:

{
"error": [
{
"message": "Invalid sort order specified in the query."
}
]
}

Exploring the Root Cause of the Issue

The root cause of the 'Invalid Sort Order' error is typically due to specifying a sort order that Weaviate does not support. Weaviate expects specific keywords for sorting, such as 'asc' for ascending and 'desc' for descending. If a different keyword or an incorrect syntax is used, the query will fail.

Supported Sort Orders

  • asc: Sorts the results in ascending order.
  • desc: Sorts the results in descending order.

Steps to Resolve the Invalid Sort Order Issue

To resolve this issue, follow these steps:

Step 1: Review Your Query

Check the query you are executing to ensure that the sort order is specified correctly. Here is an example of a correct query:

{
"query": {
"class": "Article",
"sort": [
{
"path": ["publicationDate"],
"order": "asc"
}
]
}
}

Step 2: Use Supported Keywords

Ensure that you are using 'asc' or 'desc' as the sort order keywords. Any deviation from these keywords will result in an error.

Step 3: Validate the Schema

Make sure that the attribute you are trying to sort by exists in the schema and is correctly defined. You can check your schema using the Weaviate console or API.

Additional Resources

For more information on Weaviate's sorting capabilities, you can refer to the official Weaviate Sorting Documentation. Additionally, the Schema Documentation provides insights into defining and managing your data schema.

By following these steps and ensuring that your queries adhere to Weaviate's requirements, you can effectively resolve the 'Invalid Sort Order' issue and optimize your data retrieval processes.
