Example of doing multiple indices search using react-instantsearch

Nested.js

import {
  InstantSearch,
  SearchBox as OriginalSearchBox,
  Hits
} from 'react-instantsearch';

import createConnector from 'react-instantsearch/src/core/createConnector.js';
const UseParentQuery = OriginalSearchBox.connect(() => null);
const Nested = createConnector({
  displayName: 'Nested',
  getProps: (props, state) => ({
    parentState: state,
  }),
})(props => {
  return <InstantSearch
    appId="latency"
    apiKey="6be0576ff61c053d5f9a3225e2a90f76"
    indexName="ikea"
    state={props.parentState}
    onStateChange={() => {}}
    createURL={() => {}}
  >
    <div>
      <UseParentQuery/>
      <Hits/>
    </div>
  </InstantSearch>;
});

// then you can nest <Nested/> anywhere
