I am implementing an inventory management layer with the `@azure/cosmos` library using Azure AD authentication. I need two features: a function to search items by category and price threshold using safe SQL parameters, and a safe update function that prevents overwriting modifications made by parallel requests using standard entity tags. Please produce a TypeScript class snippet that implements both methods and includes error handling for concurrency collisions.
| Checked | Without skill | With skill |
|---|---|---|
| The DefaultAzureCredential instantiation includes requiredEnvVars set to AZURE_TOKEN_CREDENTIALS. | Missed | Passed |

| The update operation sets accessCondition with type IfMatch and condition matching the ETag. | Passed | Passed |
