[Bug]:mem0 filter for metadata has syntax error; user_id, agent_id in filter is OR not AND logic

[fengyinqiao]

Mem0Client.java: private <T> Mono<String> executePostRaw(String endpoint, T request, String operationName)
after debug i found that the request body is as follow:

{"query":"xxx","version":"v2","filters":{"system":"bifrost-agent","agent_id":"BifrostDiagnosisAgent","agent_name":"BifrostDiagnosisAgent","user_id":"default","type":"diagnosis","version":"1.0.0"},"top_k":5,"user_id":"default"}

but found error:

{"filters":["Top-level key must be a logical operator or an allowed field: ['AND', 'OR', 'NOT', 'user_id', 'agent_id', 'app_id', 'run_id', 'created_at', 'updated_at', 'timestamp', 'text', 'categories', 'metadata', 'keywords_search', 'memory_ids', 'keywords']."]}

the correct syntax is expected as below:

{
  "query": "xxx",
  "version": "v2",
  "filters": {
    "OR": [
      { "user_id": "default" },
      { "agent_id": { "in": ["BifrostDiagnosisAgent"] } },
      {
        "AND": [
          { "metadata": { "system": "bifrost-agent" } },
          { "metadata": { "agent_name": "BifrostDiagnosisAgent" } },
          { "metadata": { "type": "diagnosis" } },
          { "metadata": { "version": "1.0.0" } }
        ]
      }
    ]
  },
  "top_k": 5,
  "user_id": "default"
}

also,user_id, agent_id in filter is OR not AND logic, because the message in mem0 belongs to only one entity not both:

the follow logic need to fix, i think:
