SIREn is an extension for Apache Lucene and Solr. SIREn adds new features to Lucene and Solr for processing and searching highly heterogeneous semi-structured data (e.g., RDF). In essence, SIREn adds a new "field type" with a set of specific tools such as Analyzers, Query Operators and Query Parser. If you were looking for a way to:
- have a real schema-less solution, i.e., you don't have to define all of your fields ahead of time, without penalties on the system performance;
- search efficiently over millions of fields;
- create a Lucene Document containing suub-element (i.e., nested child elements) then SIREn might be a solution for you.
SIREn extends Lucene and Solr, meaning that you can still use all the features of Solr in conjunction with the features provided by SIREn.
