This template shows how to enable full text search on firebase database elements by using an Algolia hosted search service.
See file functions/index.js for the code.
The dependencies are listed in functions/package.json.
As an example we'll be using a simple blog structure:
/functions-project-12345 /blog-posts /key-123456 text: "This is my first blog entry..." last_index_timestamp: 1234567890 /key-123457 text: "This is my second blog entry..." last_index_timestamp: 1234567891 /search /queries /key-546789 query: "first entry" /key-078234 query: "second entry" /results /key-546789 hits: [... /key-078234 hits: [... /last_query_timestamp: 1234567892 Whenever a new blog post is created or modified a Function sends the content to be indexed to the Algolia instance. To perform new searches clients add the search query to the realtime database under /search/queries/ which triggers a Firebase function which performs the search on the Algolia instance. The results are written under the /search/results/ tree.

Enable Billing on your Firebase project by switching to the Blaze plan. You need billing enabled to allow external requests. For more information have a look at the pricing page.
Set the algolia.app_id and algolia.api_key Google Cloud environment variables to match the Algolia application ID and API key of your account. For this use:
firebase functions:config:set algolia.app_id="myAlgoliaAppId" algolia.api_key="myAlgoliaApiKey"
