How to use Elasticsearch with MongoDB?

Question

I have gone through many blogs and sites about configuring Elasticsearch for MongoDB to index Collections in MongoDB but none of them was straightforward.

Please explain to me a step by step process for installing elasticsearch, which should include:

• configuration

• run in the browser

I am using Node.js with express.js, so please help accordingly.

Answer 1

To use Elasticsearch with MongoDB you can set up a single node Elasticsearch "cluster" to index MongoDB for use in a NodeJS, Express app on a fresh EC2 Ubuntu 14.04 instance and make sure everything is up to date.

sudo apt-get update

After that install NodeJS.

sudo apt-get install nodejs 

sudo apt-get install npm

Answer 2

Once you have ES installed, refer the following procedures step by step:

1. You have to generate the index for the documents.
2. Then you will be importing the collection into the ES with a tool known as mongo-connector.
3. After importing, relocate the index that was created by mongo-connector in ES to the index we created in step 1.
4. At last, try out the current index and observe how documents are indexed all the time while we have the mongo-connector running.
