Searchkit is an open source library which helps you build a great search experience with Elasticsearch. Works with Javascript, React, Vue, Angular, and more.
Website | Demos | Documentation | Discord
Searchkit provides a Search UI for Elasticsearch or Opensearch. With Searchkit, you can use Instantsearch components like Searchbox, refinement filters and results (and many more!) to build a search experience.
Searchkit is great for anyone who want to build a search experience quickly.
Searchkit simplifies Search UI with Elasticsearch:
- UI Search Components for React, Vue, Angular, and more
- Searchkit Node API proxies Elasticsearch requests from the browser.
- Ability to use Elasticsearch Query DSL for advanced queries

Either install via npm or yarn
npm install searchkit @searchkit/api @searchkit/instantsearch-clientor via CDN
<script src="https://cdn.jsdelivr.net/npm/@searchkit/instantsearch-client@latest"></script>
<script src="https://cdn.jsdelivr.net/npm/instantsearch.js@4"></script>
<script src="https://cdn.jsdelivr.net/npm/searchkit@latest"></script>Searchkit requires Elasticsearch 7.0 or higher or Opensearch 2.4 or higher.
Below we are using Docker to run Elasticsearch.
docker pull docker.elastic.co/elasticsearch/elasticsearch:8.6.2
docker network create elastic
docker run --name elasticsearch --net elastic -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e "xpack.security.enabled=false" -e http.cors.enabled=true -e "http.cors.allow-origin='*'" -e http.cors.allow-headers=X-Requested-With,X-Auth-Token,Content-Type,Content-Length,Authorization -e http.cors.allow-credentials=true -e network.publish_host=localhost -e xpack.security.enabled=false docker.elastic.co/elasticsearch/elasticsearch:8.6.2then lets add an index and some data

}'Searchkit compatible with all Instantsearch frameworks. Below is an example using react-instantsearch.
import Searchkit from "searchkit"
import Client from '@searchkit/instantsearch-client'
// import your InstantSearch components
import { InstantSearch, SearchBox, Hits, RefinementList, Pagination, RangeInput } from 'react-instantsearch';
const sk = new Searchkit({
connection: {
host: 'http://localhost:9200',
// with an apiKey
// https://www.searchkit.co/docs/guides/setup-elasticsearch#connecting-with-api-key
// apiKey: '##########'
// with a username/password
// https://www.searchkit.co/docs/guides/setup-elasticsearch#connecting-with-usernamepassword
//auth: {
// username: "elastic",
// password: "changeme"
//}
},
search_settings: {
search_attributes: [{ field: 'title', weight: 3 }, 'actors', 'plot'],
result_attributes: ['title', 'actors', 'poster', 'plot'],
highlight_attributes: ['title'],
facet_attributes: [
{ attribute: 'actors', field: 'actors.keyword', type: 'string' },
{ attribute: 'imdbrating', type: 'numeric', field: 'imdbrating' }
]
}
})
const searchClient = Client(sk);
const App = () => (
<InstantSearch

searchClient={searchClient}
>
<SearchBox />
<div className="left-panel">
<RefinementList attribute="actors" searchable={true} limit={10} />
<RangeInput attribute="imdbrating" />
</div>
<div className="right-panel">
<Hits />
<Pagination />
</div>
</InstantSearch>
}follow along with the Getting Started guide.
Searchkit Node API allows you to proxy requests to Elasticsearch from the browser. This is useful if you want to hide Elasticsearch from the browser, or if you want to add user permission filters to the query.
Searchkit has an out the box query builder, but you can also customise the query by passing a getQuery function to the apiClient.
const results = await apiClient.handleRequest(req.body, {
getQuery: (query, search_attributes) => {
return [
{
combined_fields: {
query,
fields: search_attributes,
},
},
];
},
});Searchkit supports KNN query search. Below is an example of a KNN query search.
const results = await client.handleRequest(req.body, {
getKnnQuery(query, search_attributes, config) {
return {
field: 'dense-vector-field',
k: 10,
num_candidates: 100,
// supported in latest version of Elasticsearch
query_vector_builder: {
text_embedding: {
model_id: 'cookie_model',
model_text: query
}
}
}
}
});Follow along with the Semantic Search tutorial.
You can also override the entire query with request hooks. Below is an example of a request hook that adds a rescore query to the first search request.
You can apply this at beforeSearch and afterSearch.
const results = await client.handleRequest(req.body, {
hooks: {
beforeSearch: (searchRequests) => {
const uiRequest = searchRequests[0]
return [
{
...uiRequest,
body: {
...uiRequest.body,
rescore: {
window_size: 100,
query: {
rescore_query: {
match: {
plot: {
query: uiRequest.body.query,
operator: "and",
},
},
},
query_weight: 1,
rescore_query_weight: 10,
}
}
}
},
searchRequests.slice(1, searchRequests.length)
]
},
}
});read more in the api docs here.
Query rules allows you to customize the behavior of the search experience. You can use query rules to boost or filter results, or to change the ranking of results, based on a set of conditions.
Below is an example of a query rule that boosts results for movies with Dan Aykroyd or Charlie Sheen, and filters results to only show movies if the query is the word "movie".
{
id: '1',
conditions: [
[
{
context: 'query',
value: 'movie',
match_type: 'exact'
}
]
],
actions: [
{
action: 'QueryBoost',
query: 'actors:"Dan Aykroyd" OR actors:"Charlie Sheen"',
weight: 2
},
{
action: 'QueryFilter',
query: 'type:"movie"'
}
]
}read more at Query Rules docs.

Q: Do I need to expose Elasticsearch to the public internet?
Searchkit proxies requests to Elasticsearch.
Searchkit offers both options, either perform the search directly from the browser, or use the Searchkit API to proxy requests to Elasticsearch. Directly from the browser offers great developer experience & prototyping. Once you are ready to deploy, you can use the Searchkit API to proxy requests to Elasticsearch.
Q: Do I need to use React?
You can use React, React Native, Vue, Angular. You dont even need to use a frontend framework, you can use plain Javascript and HTML with instantsearch.js widgets.
Q: Which version of Elasticsearch is supported?
Searchkit is compatible with Elasticsearch 7.0 and above + Opensearch 2.0 and above.
Q: Do you support Android and iOS?
Potentially. Searchkit API mimics the Algolia API, so it should be possible to use the Algolia Instantsearch client with Searchkit API with a few tweaks. If you are interested in this, please let us know.
Q: Why would I use Searchkit instead of Algolia?
Elasticsearch has alot of advantages over Algolia. You might want to use Elasticsearch as a cheaper alternative to Algolia, especially if you have a large dataset. You might want to run Elasticsearch on your own infrastructure, or have greater control over the query relevance.
