Graph queries filtered every token with len > 2, which dropped common two-character Chinese search terms while trying to suppress short English noise. Centralize query token selection and apply the length gate only to pure-English tokens so mixed or non-English terms remain searchable.
Constraint: Issue #962 reports space-separated Chinese query terms such as 前端, 依赖, and 安装 are lost by graphify query.
Rejected: Add Chinese segmentation now | the reported failure is fixed by preserving existing space-separated non-English tokens without expanding query behavior.
Confidence: high
Scope-risk: narrow
Directive: Keep CLI, MCP query, and benchmark query tokenization on one helper when changing query-term rules.
Tested: uv run --with pytest pytest tests/test_serve.py tests/test_query_cli.py tests/test_benchmark.py
Tested: graphify update .
Not-tested: Full test suite.
