What's New

YAML Configuration System

All settings are now customizable via config.yaml — no more editing Python code. Categories, keyword routing, query expansions, models, chunking, and paths are all configurable through a single YAML file.

Domain Presets

Four ready-to-use presets ship with the project:

| Preset | Categories | Keywords | Expansions | Best For |
|--------|-----------|----------|-----------|----------|
| cybersecurity | 8 | 200+ | 69 | Red/Blue Team, CTFs, threat hunting |
| developer | 9 | 150+ | 50+ | Full-stack, APIs, DevOps, cloud |
| research | 9 | 100+ | 40+ | Academic papers, thesis, datasets |
| general | 0 | 0 | 0 | Blank slate, pure semantic search |

cp presets/developer.yaml config.yaml   # Ready to go

Generic Use Support

With empty mappings ({}), the system operates as a domain-agnostic semantic search engine. No security-specific logic unless you want it.

Backwards Compatible

No config.yaml? The system uses built-in defaults — identical behavior to v3.2.x. Zero migration required.

Changes

• NEW: YAML configuration system — fully customizable via config.yaml
• NEW: Domain presets — cybersecurity, developer, research, general
• NEW: config.example.yaml — documented template with explanations for every field
• NEW: Categories, keyword routing, and query expansions now user-configurable
• NEW: Empty config = pure semantic search with zero domain logic
• NEW: Warning log for empty files during indexing (previously silent skip)
• IMPROVED: README rewritten — full configuration reference, preset docs, updated structure
• IMPROVED: pyyaml added as dependency

Upgrade

git pull origin master
pip install pyyaml    # New dependency
# Optionally: cp presets/cybersecurity.yaml config.yaml

No breaking changes. Existing installations work without any config file.
