# Industrial Specification: Query Engine

## 1. Technical Definition
A software component that processes search requests and retrieves relevant data from a file index database.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-1000 queries/second**. Failure boundary: **Query latency exceeding 5000 ms or memory usage exceeding 95% of allocated 16 GB RAM**, Mechanism: **Memory bandwidth saturation at 25.6 GB/s causing cache thrashing and thermal throttling at 85°C junction temperature**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Memory leak accumulating at 2 MB/minute | 8 | Heap exhaustion causing process termination at 16 GB limit | Implement reference counting with garbage collection at 80% heap utilization |
| Index corruption from write operation during concurrent read at 1000 IOPS | 8 | Query returning inconsistent results with 15% error rate | Implement MVCC with snapshot isolation at transaction level |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |
| :--- | :--- | :--- | :--- |
| spec | Config-dependent | queries/sec | Verified |
