Your web.
Your bots.
Your workflows.
Build custom search bots that crawl the web, filter signal from noise, and automate your daily research — all in one command center.
Welcome to NetSearch Systems—an open architecture research hub and programmable search engineering platform delivering high-throughput web crawling, distributed inverted indexing, and hybrid neural information retrieval.
Core Search Engineering Disciplines
- Distributed Web Crawling & Frontier Queues: High-concurrency asynchronous URL frontiers with per-host politeness rate limiting, robots.txt AST validation, and high-speed DNS caching.
- Inverted Indexing & Posting Compression: Compact posting list encoding using Elias-Fano, Roaring Bitmaps, and Block-WAND dynamic pruning algorithms.
- Lexical & Neural Hybrid Retrieval: Combining Okapi BM25 term saturation scoring with dense vector embeddings (HNSW) and cross-encoder transformer re-ranking.
- Real-Time Stream Indexing: LSM-tree write-ahead log buffers, immutable segment flushes, and background tiered merging for sub-millisecond document visibility.

One platform. Infinite searches.
netsearch.me combines bots, workflows, and a private search index into a single, programmable research layer.
Custom search bots
Spin up bots for any topic. Teach them domains, keywords, and sources. They never sleep.
Visual workflows
Chain bots, filters, and actions into drag-and-drop automation pipelines.
Personal search index
Everything your bots find is indexed privately. Query it like your own mini-Google.
Smart filters & alerts
Cut through the noise with AI-powered relevance scoring and real-time notifications.
API & integrations
Connect to Slack, Notion, Discord, Zapier, or your own backend with a clean REST API.
From idea to insight in minutes
No complex setup. No coding required to start. Build your first bot and see results today.
