You can use Algolia to full text search your Firebase data – this is done by mirroring the posts in an index which can easily be maintained by setting up Cloud Functions to do it for you.

import * as algolia from 'algoliasearch'
import { config, firestore } from 'firebase-functions'

const { app_id, api_key } = config().algolia
const postsDocument = firestore.document('posts/{postId}')
const postsIndex = algolia(app_id, api_key).initIndex('POSTS')
const toObject = (snap) => ({ objectID: snap.id, ...snap.data() })

export const onCreatePost = postsDocument.onCreate((snapshot, context) => {
    return postsIndex.saveObject(toObject(snapshot))
});

export const onUpdatePost = postsDocument.onUpdate((snapshot, context) => {
    return postsIndex.saveObject(toObject(snapshot.after))
})

export const onDeletePost = postsDocument.onDelete((snapshot, context) => {
    return postsIndex.deleteObject(snapshot.id)
})
