Search entities

Performs a filtered search over Entities using a POST request.
This endpoint supports the same filtering capabilities as GET /v2/entities, but allows a larger and more complex payload.
It's useful when filtering by a long list of foreign key IDs or when URL length limits become a problem.

Limitations

• Only the AND operator is supported when applying multiple filters. OR, NOT, or nested conditions are not supported.
• You can search only within one entity type at a time.
