Lucene

The Lucene full-text index provided by the triplestore is used to perform full-text searches in DSP.

Lucene Query Parser Syntax

Full-text searches in DSP are based on Lucene. Therefore, full-text searches support the Lucene Query Parser Syntax.

A full-text search consists of a single word in the simplest case, but could also be composed of several words combined with Boolean operators. By default, Lucene combines two or more terms separated by space with a logical OR.

For examples, see Lucene Query Parser Syntax.
