'''LuisSearch''' is a real, independently-built search engine covering both general web content and a dedicated image index, alongside AI-assisted features layered on top of classic keyword search.

== Features ==
* '''Web search''' -- a from-scratch crawler and BM25-style ranking index over crawled pages, with a Host Name Boost that surfaces official domains (e.g. docs.docker.com for a 'docker' query) higher in results
* '''Image search''' -- a separate crawler indexes <code>&lt;img&gt;</code> alt text from crawled pages into its own database, with thousands of images indexed
* '''AI reranking''' -- a local LLM reranks the top candidates from the keyword index for queries longer than a couple of words, falling back to plain keyword order if the AI call times out
* '''Public API''' -- documented endpoints for search, image search, and account/API-key management, with tiered rate limits (none/free/account/plus)
* '''Nexus''' -- a real-time chat feature built into the same codebase, using long-polling rather than WebSockets or Server-Sent Events (the Cloudflare tunnel LuisSearch runs behind buffers SSE, so long-polling was used instead)
* '''AI-generated sites''' -- users can describe a small site or app and have it generated, deployed, and hosted directly from the platform

== Architecture ==
LuisSearch runs as a single Python stdlib <code>http.server</code>-based backend (no framework), backed by SQLite for its indexes, accounts, and logs. The public-facing domain is a Cloudflare Pages deployment whose <code>_worker.js</code> proxies API traffic through to the real backend, which itself runs behind a <code>cloudflared</code> tunnel rather than being hosted directly on Cloudflare's own compute.

== History ==
The image search feature and public API were both added as later milestones after the core web search was already live, expanding LuisSearch from a plain keyword search tool into a small multi-purpose platform combining search, chat, and AI-assisted site generation.
