basically, I know the difference between MongoDB and the ES. In my server I have installed MongoDB instance separately will name it as (MDB1) and I installed ES instance separately will name it as (ESS). Currently, I am working on document management system, daily storing millions different kind of document information in Mongo DB. I have browsed many websites but I didn't get my answer as expected.
My question is, I want to connect ESS to MDB1, coz I using ES to search and analyze the data. Is there have any method to connect ES to existing MongoDB instance. (I am using C#.net)

There is no official connector from the Elasticsearch side. There are third-party connectors you can use. You can also do http bulk update queries to load data to ES.

**Configure MongoDB on Elasticsearch**
1. Install MongoDB
2. Configure MongoDB
```auto
net:
bindIp: 127.0.0.1
port: 27017
replication:
oplogSizeMB: 1024
replSetName: res0
storage:
dbPath: C:\data\db\rs0
systemLog:
timeStampFormat: iso8601-utc
destination: file
path: C:\data\log\rs0\mongod.log
```
- Create two file using above configuration save it as `primary.cfg` and `secondary.cfg`.
- Install as Service:
```auto
mongod --config "C:\Program Files\MongoDB\Server\3.6\primary.cfg" --install --serviceName "MongoDB_Primary" --serviceDisplayName "MongoDB Primary"
mongod --config "C:\Program Files\MongoDB\Server\3.6\secondary.cfg" --install --serviceName "MongoDB_Secondary" --serviceDisplayName "MongoDB Secondary"
```
- Start services (Primary and Secondary instances):
1. Connect to the primary database
2. Use `rs.initiate()` command
3. Use `rs.add("127.0.0.1:27018")` command
4. Use `rs.config()` command
5. Use `rs.status()` command
6. Install Java latest version and set java home path in variable environment
7. Install Elasticsearch
8. Go to Elasticsearch folder and open config folder
9. Set following configuration in `elasticsearch.yml` file:
```auto
cluster.name: home_server
node.name: gehan-pc
path.data: C:\Elasticsearch\data
path.logs: C:\Elasticsearch\logs
network.host: 127.0.0.1
network.bind_host: 0.0.0.0
http.port: 9200
http.cors.enabled : true
http.cors.allow-origin : "*"
http.cors.allow-methods : OPTIONS, HEAD, GET, POST, PUT, DELETE
http.cors.allow-headers : X-Requested-With,X-Auth-Token,Content-Type, Content-Length
```
1. Install following files:
```auto
pip install mongo-connector[elastic5]
pip install elastic2-doc-manager[elastic5]
```
1. Start Elasticsearch instance
2. Run this command:
```auto
mongo-connector --auto-commit-interval=0 -d elastic_doc_manager -t localhost:9200
```
1. Open [http://localhost:9200/\_cat/indices?v](http://localhost:9200/_cat/indices?v) to check is mongo collections sync with Elasticsearch server

Thank you @Gehan_Fernando for sharing your recipe. I updated the format a bit as this can be useful for other members. I hope I did not change anything important (specifically, I updated a bit the mongo config).
