BioSolr is a tool that enriches Solr or Elasticsearch indexes with ontology knowledge.
It enhances documents that have been annotated with ontology terms by pulling in the ontology structure of the terms from the Ontology Lookup Service
This area contains plugins related to ontologies, including search engine plugins for enriching documents with ontology data.
This is a webapp build to explore the enriched documents that have been indexed using BioSolr Ontology Expansion plugins found in the ontology directory.
You will find short interactive introductions to the BioSolr Ontology Expansion plugin, one for Solr and one for Elasticsearch.
