What is SIREn ?

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.

Does SIREn support Faceted Search ?

Yes, you can create arbitrary facets using SIREn's query with the Solr Query Faceting feature.

Does SIREn support highlighting ?

Yes, SIREn support highlighting.
