Elasticsearch

This page describes how to connect to your Elasticsearch database and query it from your Appsmith app.

Connect Elasticsearch​

caution

If you are a cloud user, you must whitelist the IP address of the Appsmith deployment 18.223.74.85 and 3.131.104.27 on your database instance or VPC before connecting to a database. For instructions on IP Filtering in Elasticsearch, see the Elasticsearch docs.

Connection parameters​

The following is a reference guide that provides a description of the parameters for connecting to Elasticsearch.

Connect to Elasticsearch
Connect to Elasticsearch

Host URL​

The network location where your Elasticsearch data is hosted. This can be a domain name or an IP address. To connect to a local database, see Connect Local Database for directions.

Port​

The port number to connect to on the server.

Username/Password for Basic Auth​

The account credentials used to log in to Elasticsearch.

Authorization Header​

Instead of the username/password fields, you can provide an Authorization Header to authenticate your queries. This field is only used when the Username/Password for Basic Auth fields are empty.

Query Elasticsearch​

The following section provides examples of creating basic CRUD queries to Elasticsearch.

info

For details on building more complex queries, see the Elasticsearch Document API documentation.

Method​

The HTTP method to use for your query.

Options:
  • GET: Method used for requesting and fetching data.
  • POST: Method used for creating or updating records.
  • PUT: Method used for creating or updating records.
  • DELETE: Method used for deleting records.

Path​

The endpoint to which your query is sent. This usually is made up of the index name and the name of an operation. For example: /users/_search is the endpoint used for searching the users index.

Body​

The body content of your query.

Search documents​

Queries run on top of indexed documents can be configured using the GET method.

Path:

/users/_search

Body:

{
  "query": {
    "match": {
      "user.name": {{ UsersTable.searchText }}
    }
  }
}

The example above searches the users index for a name matching your user input from a Table widget called UsersTable.

Create a document​

You can create a single new document using the POST method, with a JSON body that represents the document values; an id is automatically generated.

Path:

/users/_doc/

Body:

{
    "name": {{ NewUserForm.data.Name }},
    "email": {{ NewUserForm.data.Email }},
    "gender": {{ NewUserForm.data.Gender }},
}

Above, user input is collected with a Form widget called NewUserForm.

Update a document​

A single document can be updated using its id within an index using a POST request.

Path:

/users/_update/{{ UsersTable.selectedRow.id }}

Body:

// using a JSON Form widget to collect input
{
  "doc": UpdateUserForm.formData
}

Above, the record with its id is selected from a Table widget called UsersTable and updated with input from a JSON Form widget.

This performs a partial update, where the properties you supply are added to the document; you don't need to add ones that have not changed.

Delete a document​

A single document can be deleted using its id within an index using the DELETE method.

Path:

/users/_doc/{{ UsersTable.selectedRow.id }}

Above, the record with its id is selected from a Table widget called UsersTable.
