First public release of Torque — Truespar's in-memory search engine. Typesense v30.1 API compatible.

Full-text search with relevance ranking and multi-field queries
Filters: exact match, numeric range, boolean, array, geo radius, and nested object conditions
Sorting: field, text relevance, geo distance, and decay functions (Gaussian, linear, exponential)
Faceted search with stats (min, max, sum, average)
Grouping with configurable per-group limits
Prefix / autocomplete search
Typo tolerance with automatic correction
Vector search (dense embeddings) with hybrid relevance blending
Synonyms (bidirectional and root), presets, stopwords
Highlighting with configurable tags
Stemming for 17 languages: English, German, French, Spanish, Portuguese, Italian, Dutch, Swedish, Norwegian, Danish, Finnish, Russian, Arabic, Greek, Hungarian, Romanian, Turkish

HTTP JSONL import — Typesense-compatible import endpoint with create, upsert, and update actions
TCP binary ingest — custom high-throughput streaming protocol for live database sync (70K docs/s measured on a 309K-document benchmark, 9.5× faster than Typesense on the same hardware)
TQBF binary file upload — pre-encoded compressed file format for bulk imports, ETL pipelines, and data distribution
Batch mode for full index rebuilds on commit
Realtime mode for instant upsert and delete with backpressure handling

Typesense v30.1 compatible HTTP REST API — drop-in replacement for existing Typesense clients
Full collection CRUD, document CRUD, search, multi-search, aliases, API key management
Collection aliases for zero-downtime schema migrations
HMAC scoped search keys

Full in-memory serving with automatic disk persistence
Realtime overlay persistence with sub-second flush
Atomic writes with integrity checks (temp file + fsync + rename)
Automatic collection, schema, alias, key, synonym, preset, and stopword restore on startup

TLS / HTTPS support
Prometheus metrics endpoint at /metrics
HTTP IP allowlist via --allowed-ips / TORQUE_ALLOWED_IPS (CIDR ranges)
Configurable collection deletion guard (allow_drop_collection) for production hardening
Configurable Studio gating (--no-studio) for API-only deployments
Auto-generated bootstrap API key on first run (persistable via --api-key, env var, or TOML)
Slow query logging with configurable threshold
Multi-node failover and retry across nodes (configured client-side)
SIGTERM graceful shutdown (Docker and systemd compatible)
Daily rotating log files
Windows Service support (--service-install / --service-uninstall)
TOML configuration file, environment variables, and command-line arguments

NVIDIA CUDA acceleration for scoring, filtering, vector distance, and facet counting
