Did you know that GraphDB™ Enterprise Edition comes with Connectors for Lucene, SOLR and ElasticSearch? These Connectors provide extremely fast keyword and faceted (aggregation) searches that are typically implemented by an external component or service, but have the additional benefit of staying automatically up-to-date with the GraphDB™ repository data.
The Connectors provide synchronization at the entity level, where an entity is defined as having a unique identifier (URI) and a set of properties and property values. In terms of RDF, this corresponds to a set of triples that have the same subject. In addition to simple properties (defined by a single triple), the Connectors support property chains. A property chain is defined as a sequence of triples where each triple’s object is the subject of the subsequent triple.
We’re hopeful that these insights into GraphDB™ Search Connectors have been of use. Please contact us if you have questions about this or any other topic during your evaluation.
