Search index: Configuring Elasticsearch

Elasticsearch is supported from version 1.4.0 (using the elasticSearch connector) and for version 2.x and version 5.x (using the elasticSearch2 connector).

Elasticsearch 6 is not yet supported in Linkurious 2.2.2.

Embedded Elasticsearch

Linkurious ships with an embedded Elasticsearch server (version 1.4.5).

To use the Linkurious embedded Elasticsearch instance, set the following index configurations keys:

  • vendor must be elasticSearch
  • host must be "127.0.0.1"
  • port must be 9201

Example configuration:

{
  "dataSources": [
    {
      "graph": {
        "vendor": "neo4j"
        "url": "http://127.0.0.1:7474"
      },
      "index": {
        "vendor": "elasticSearch",
        "host": "127.0.0.1",
        "port": 9201
      }
    }
  ]
}

Configuring Elasticsearch v1.x

Search connector elasticSearch supports the following options:

  • host (required): Elasticsearch server host
  • port (required): Elasticsearch server port (standard is 9200)
  • https: true to connect to Elasticsearch via HTTPS
  • user: Elasticsearch username (if you are using X-Pack Security, a.k.a ElasticShield)
  • password: Elasticsearch password
  • forceReindex: true to re-index the data-source each time Linkurious starts
  • skipEdgeIndexation: true to skip edges indexation (edges won't be searchable)
  • analyzer (default: "standard"): The custom analyzer aimed at analyzing a specific language text. (see available language analysers)
  • dynamicMapping: true to enable number parsing for advanced number search features (range, etc.)
  • dateDetection: true to enable date parsing for advanced date search features (range, etc.)

Example configuration:

{
  "dataSources": [
    {
      "graph": {
        "vendor": "neo4j"
        "url": "http://127.0.0.1:7474"
      },
      "index": {
        "vendor": "elasticSearch",
        "host": "192.168.1.80",
        "port": 9200,
        "dynamicMapping": false
      }
    }
  ]
}

Configuring Elasticsearch v2.x

Search connector elasticSearch2 supports the following options:

  • host (required): Elasticsearch server host
  • port (required): Elasticsearch server port (standard is 9200)
  • https: true to connect to Elasticsearch via HTTPS
  • user: Elasticsearch username (if you are using X-Pack Security, a.k.a ElasticShield)
  • password: Elasticsearch password
  • forceReindex: true to re-index the data-source each time Linkurious starts
  • skipEdgeIndexation: true to skip edges indexation (edges won't be searchable)
  • analyzer (default: "standard"): The custom analyzer aimed at analyzing a specific language text. (see available language analysers)
  • dynamicMapping: true to enable number parsing for advanced number search features (range, etc.)
  • forceStringMapping: List of fields that are mapped to strings even with dynamicMapping is true
  • caCert: Absolute path to a Certificate Authority certificate

Example configuration:

{
  "dataSources": [
    {
      "graph": {
        "vendor": "neo4j"
        "url": "http://127.0.0.1:7474"

        "vendor": "elasticSearch2",
        "host": "192.168.1.122",
        "port": 9200,
        "skipEdgeIndexation": true
      }
