2 min read

ReactiveSearch for React 4.0 is a major update for the React UI kit and provides several enhancements for building AI native user interfaces and search experiences.

Watch the 1-min introduction video below: ๐Ÿ‘‡

New Components

AI Answer

The AIAnswer UI component enables building a RAG (retrieval augmented generation) based chat experience with AI answering support. See a demo in action over here. Or read the component's documentation reference over here.

The SearchBox component is enhanced to support AI Answering, image searching, showing FAQs as suggestions, and showing curated suggestions with custom actions. See all of these in action with an extensive search showcase below. Read the component documentation over here.


Embed reactive charts in your search interface. With 5 built-in chart types: pie, bar, scatter, line and histogram supported and use ReactiveChart to support any chart UI using Apache E-charts.

Simplified SSR

With ReactiveSearch v4, configuring SSR is an intuitive experience by removing the requirement of providing the component configuration.

Secure API

ReactiveSearch v4 uses the ReactiveSearch API introduced in v3 to express the search intent. This requires the use of a ReactiveSearch server with two initial deployment choices: a search cluster and a serverless search mode.

Expanded Search Engine Support

ReactiveSearch UI kit supports Elasticsearch, OpenSearch, OpenAI, Solr and MongoDB Atlas Search as the choices for backend search engines.

Search EngineSearch Cluster SupportServerless Search support
ElasticsearchYes, fully hostedYes (user connects to their Elasticsearch)
OpenSearchYes, fully hostedYes (built-in)
OpenAIYes, API support and via pipelinesYes, API support via pipelines
Solr [Preview]-Yes (user connects to their Solr cloud cluster)
MongoDB Atlas Search [Preview]-Yes (user connects to their MongoDB Atlas Search cloud)

Elasticsearch and OpenSearch are supported completely. OpenAI is supported with both ReactiveSearch API and with pipelines. Solr and MongoDB Atlas search supports are in preview, we're happy to provide additional support to get you up and running with these engines.

I'm excited to see what you build with ReactiveSearch v4! You can check out the developer quickstart guide and star the project at
