Search index: DataStax Enterprise Graph

The dseSearch connector is the recommended solution for full-text search for graphs with more than 100,000 nodes and edges.

DataStax Enterprise Graph Search integration

Linkurious can use the builtin search indices managed by DataStax Enterprise Graph itself. You can either use the Web user-interface or edit the configuration file located at linkurious/data/config/production.json to set the index.vendor property to the value dseSearch.

See the DataStax Enterprise Graph documentation to learn more.

If you already have a search index in DataStax Enterprise Graph, the following step is not required.

Index with DSE Search

Please refer to the DataStax Enterprise Graph documentation on how to create new indices, including search indices.

Follow these steps to use DSE Search and integrate it with Linkurious:

  1. Connect via gremlin to DSE Graph
  2. For each node label you want to index execute this command:

Every property key that you want to index has to appear in this command. You can add as many properties as you want. We recommend to index only what you actually need to.

We recommend to create asText() search indices instead of asString() ones. Both types of indices are supported by Linkurious, but the latter doesn't support OR search queries. If you don't need this feature, asString() indices will actually compute search queries faster. It's also possible to mix asText() and asString() indices to find a balance of features and performances.
