A live hotel search box, and a demo of searching hotels by sentence.

A hotel search starts with a place. The traveller types a city, an area, a landmark, an airport, an island or a hotel name, and the site has to resolve it before it can show anything. Autosuggest does that step. The harder step comes next: a traveller who knows the place often describes the hotel rather than naming it, by star rating, area, theme or a must-have amenity. The search demo shows how Plexe handles that second step.

Autosuggest ships as @plexe/autosuggest, a web component with no dependencies plus a React wrapper, loaded from suggest.plexe.ai with one script tag or installed from npm. Each suggestion carries its coordinates and hotel count, and its id opens the place's hotels in the API. Website keys list the domains they may be used on, so they are safe in page code, and the free tier covers up to 5,000 requests a day.

The component handles the details that make a search box feel quick. The first keystroke is sent at once and later ones are spaced by a 120 ms debounce; a new request cancels the one in flight, and late answers to old text are dropped. Arrow keys, Enter and Escape work, and screen readers hear the list. Each pick is reported back to tune the ranking, and a site can switch that reporting off.

The natural-language demo indexes 1,652 hotels in a resort region, 335 of them enriched with review summaries from a review provider. Claude Haiku 4.5 reads the query and extracts minimum stars, sub-area, themes, property type and must-have amenities. A rewritten version of the query is embedded with Cohere on AWS Bedrock and matched in ChromaDB, then a weighted rerank combines similarity, at 0.65, with review, star, theme and amenity signals.

Two design choices keep results honest. Star rating is a soft boost rather than a hard filter, so a search never comes back empty, and the interface shows the traveller what was inferred. Hotels without reviews are labelled “no reviews yet” instead of being scored as poor. A Next.js console sits on top of the engine to tune rerankers, run experiments and evals, and manage datasets.

Autosuggest is a live product: anyone can sign up at suggest.plexe.ai, create a website key and add the box to a page with one script tag. The natural-language search is a demo over a fixed set of hotels, without prices or availability, and image search and a map view are listed as outside its first version. No accuracy or usage figures have been published for either part yet.
