# Industrial Specification: Query Parser

## 1. Technical Definition
A software component that analyzes and interprets user search queries to extract structured information.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-1000 queries/second**. Failure boundary: **Query complexity exceeding 256 nested logical operators or input length &gt; 1MB**, Mechanism: **Computational complexity explosion (O(n²) parsing algorithm) causing CPU thermal throttling at 95°C junction temperature**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Unicode normalization failure in UTF-8 decoder | 8 | Character encoding corruption producing semantic parsing errors | Implement Unicode 13.0 compliant preprocessor with fallback ASCII mapping |
| Regular expression backtracking exceeding 10⁶ operations | 8 | Parser thread deadlock at 100% CPU utilization for 30 seconds | Convert regex patterns to deterministic finite automata with O(n) complexity guarantee |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |
