Linkurious Enterprise allows you to search your graph using natural full-text search.
In order to offer the search feature out-of-the-box, Linkurious Enterprise ships with an embedded Elasticsearch server. This option allow for zero-configuration deployment in many cases.
Indexing your graph data
By default, Linkurious Enterprise uses Elasticsearch for search. This options requires Linkurious Enterprise to index your graph database, which technically means that Linkurious Enterprise will feed the whole content of the graph database to Elasticsearch to make it searchable. The time required to index the graph database increases with the size of the graph and this solution has limits in its scalability.
Indexation typically happens at speeds between 2000 and 20000 nodes or edges per second, depending on the number of properties for nodes and edges, and hardware performances.
By default, Linkurious Enterprise ships with an embedded Elasticsearch server (version 7.16.3).
This server only listens for local connections on a non-default port (it binds to
for security reasons and to avoid collisions with existing servers.
Use your own Elasticsearch
It is possible to use your own Elasticsearch cluster for performances reasons. Linkurious Enterprise supports Elasticsearch v1.x and v2.x. See details about Elasticsearch configuration options.
Search scalability and alternatives to Elasticsearch
Using Elasticsearch is convenient but may not fit cases where the graph database is big (more than a couple million nodes and edges) and is regularly modified from outside Linkurious Enterprise, which required to re-index the whole database.
In order to offer a scalable search feature on big graphs, Linkurious Enterprise offers alternatives search solution. See details about the different options.
